Her Majesty the Queen v. Wayne Burnett
2005 CanLII 28532 (ON SC)
Superior Court of Justice - Ontario — Justice Durno | August 15, 2005
Background
Wayne Burnett was charged with assault after allegedly beating up a fellow employee at his workplace. The incident cost him his job — he received a termination letter from his employer prohibiting him from returning to the workplace. With no income, Burnett applied for legal aid but was refused. He then spent several months trying to scrape together enough money to retain private counsel, Douglas Lent.
When Lent finally came on board, he asked for multiple 3-4 week adjournments before setting a trial date — standard practice for lawyers who want full payment before proceeding. The case was eventually scheduled for what should have been a three-hour trial, but the justice of the peace misread the form and announced it would be a one-hour trial. After running 90 minutes on the first day without finishing, the trial had to be adjourned to a new date months later.
Issues
Did the trial judge err in granting a stay of proceedings under s. 11(b) of the Charter for unreasonable delay?
Should delay caused by the accused's financial difficulties in retaining counsel count against the Crown in the s. 11(b) analysis?
The 11(b) Delay Analysis
The Crown appealed the trial judge's decision to stay the charges, arguing that Burnett had deliberately delayed the proceedings and shouldn't benefit from his own conduct. Justice Durno disagreed. The court found that while Burnett's actions did cause delay, there was no evidence he was "truly malingering" or deliberately trying to build up delay for a later Charter application.
The court recognized two different approaches lawyers take to retainers: some will get on the record immediately with just a deposit, while others (prudently) want full payment before setting trial dates. Burnett's lawyer chose the latter approach, which is legitimate practice — not a scheme to create delay. As Justice Durno noted, "it would only be if there was a finding that defence counsel was somehow complicit in a scheme to build up delay for later trial delay use, that the adverse inference could be drawn."
The court also found that the trial judge had incorrectly attributed Burnett's difficulty retaining counsel to his bail conditions, when in fact he was prohibited from his workplace by his employer, not the court. However, this error didn't affect the overall s. 11(b) analysis, which properly categorized the pre-counsel period as "neutral time" rather than systemic delay.
Key Takeaway
Financial hardship that delays your ability to retain counsel won't automatically defeat a Charter delay application, provided you're not deliberately gaming the system.
If you're struggling to afford a lawyer and it takes time to get representation, that delay is considered "neutral" — it doesn't count for or against you in an 11(b) application. The key is acting in good faith throughout the process.
Ontario Court of Appeal27 February 2026turn not in safety
York (Regional Municipality) v. Wadood Court of Appeal for Ontario — Justice Laskin (Sharpe and Miller JJ.A. concurring) January 19, 2017 | 2017 ONCA 45
Background
Two defendants. Two tickets. Two officers who realized after handing over the offence notice that the certificate still sitting in their hands wasn't quite right.
Wadood got tagged for an unsafe turn. The officer forgot to fill in the municipality — "City of Vaughan" — on the certificate. So he added it before filing. Davis got nailed for doing 149 in a 100 zone. Wrong year on the certificate — 2012 instead of 2013. Officer corrected it before filing. Both defendants asked for a trial. Neither showed up. Both got convicted in absentia under s. 9.1 of the POA after a justice of the peace reviewed each certificate, found them complete and regular on their face, and did exactly what the statute required.
Both appealed. The appeal judge at the Ontario Court of Justice allowed both appeals — not because either defendant was misled, he actually said the opposite — but because in his view the amendments had been made "without authority." The Regional Municipality of York took it to the Court of Appeal. Leave was granted. The jurisprudence was a mess and the question was going to keep coming up.
Time to settle it.
Issues
Does anything in the Provincial Offences Act prohibit an officer from amending a certificate of offence after serving the offence notice but before filing it with the court?
Did s. 90 of the POA preclude the appeal judge from invalidating the convictions?
The Legal Framework
Here's the architecture. When a defendant is served with an offence notice, they have four moves: plead guilty in writing, appear to make penalty submissions, request a trial, or do absolutely nothing. Options three and four both eventually land the matter before a justice of the peace examining the certificate of offence. In a s. 9.1 proceeding — where the defendant asked for a trial and then didn't show — the justice has one job: look at the certificate. Complete and regular on its face? Convict. Not complete and regular? Quash. That's the whole menu.
Critically, the justice only has the certificate in front of them. The offence notice — the carbon copy the defendant walked away with — is not before the court. So any variance between the two documents is invisible at that stage. The presiding justice has no way of knowing one was ever changed.
Once the certificate is filed with the court, only the court can touch it. That's explicit in r. 15(1)2 of the Rules of the Ontario Court (Provincial Division). But before filing? The POA says nothing. And that silence matters.
The Court of Appeal's Analysis
Laskin J.A. refused to imply an amendment power into s. 90, as the Municipality argued. That's not what s. 90 does. It's a curative provision — it protects the validity of proceedings against defects and variances, not a source of pre-filing authority. And s. 90 doesn't even apply in ss. 9(1) or 9.1 proceedings because the offence notice never comes before the court. You can't compare two documents when only one of them is in the room.
But here's where the court breaks from the line of trial decisions that had been quashing certificates left and right: the absence of express authority is not the same as a prohibition. Nothing in the Act or the rules says an officer cannot amend the certificate before it's filed. Proceedings haven't commenced yet — that doesn't happen until filing. The officer is still in possession of their own document. Correcting a clerical error at that stage isn't mischief. It's housekeeping.
The court reviewed the conflicting trial-level jurisprudence directly. Pawar, Nandalall, Koza, McGonigal — all quashing certificates for pre-filing amendments, none of them engaging with s. 90. Aristidou and Mirza on the other side, correctly recognizing that obvious errors corrected before filing don't automatically doom a prosecution. The Court of Appeal sided with the latter approach, and went further by anchoring it in the purpose of the Act itself: decide cases on their merits, handle the province's enormous volume of regulatory offences efficiently, and don't let technical objections kill proceedings that caused no actual prejudice to anyone.
Whether a pre-filing amendment invalidates a conviction depends on two things: the nature of the change and its impact on the defendant. Where the amendment corrected a minor clerical error — a missing municipality, a wrong year — and the defendant knew exactly what charge they were facing, s. 90(1)(b) steps in and preserves the proceeding. The appeal judge had found as much on the facts. He just failed to apply the legal consequence that followed from his own finding.
That was an error of law. A straightforward one.
Decision
Appeal allowed. Convictions restored against both Wadood and Davis.
Key Takeaways
Wadood is the definitive word from the Court of Appeal on pre-filing amendments to certificates of offence, and it cuts through years of inconsistent trial-level decisions with a clean, principled rule.
An officer who spots an error on their certificate after handing over the offence notice is not stuck with it. There is no prohibition on correcting that error before filing. The proceeding hasn't started yet. The document is still theirs to fix.
What determines the outcome is not the fact of the amendment — it's the impact. If the defendant was misled or prejudiced by the change, s. 90 won't save it and the court has tools to respond. If the defendant wasn't misled — if they knew the charge, knew the date, knew exactly what they were facing — then a minor clerical correction doesn't touch the validity of the conviction. Section 90(1)(b) handles it.
Read Wadood alongside Dopp and the line becomes clear. A blank section number field is a structural defect — the certificate doesn't tell you what law was broken, and no one can fill that in when the defendant isn't there. A wrong year or a missing municipality that nobody was confused by? That's a clerical error, and the Court of Appeal has told you exactly how to treat it.
The certificate either misleads or it doesn't. If it doesn't, the conviction stands.
[2003] (Information No. not provided)
Ontario Court of Justice — Justice J.A. Fontana | January 14, 2003
Background
Lisa Hamilton was stopped by police and clocked at 147 km/h in a 100 km/h zone using radar. However, the officer exercised his discretion and only charged her with speeding at 119 km/h — a reduction of 28 km/h from what the radar actually showed. Hamilton believed she wasn't guilty and exercised her right to go to trial rather than pay the ticket.
At trial on September 13th, the Crown prosecutor A. Colterman called evidence showing that Hamilton had actually been travelling 147 km/h. After presenting this evidence, the Crown requested that the Justice of the Peace amend the certificate from 119 km/h to 147 km/h to match what the officer had actually observed on radar. The Justice of the Peace granted the amendment, convicted Hamilton of speeding at 147 km/h, but kept the fine the same. Hamilton appealed to Superior Court.
Issues
Whether the Justice of the Peace properly exercised discretion in allowing the Crown to amend the certificate after the evidence was presented
Whether Hamilton was prejudiced by having to defend against a more serious charge than what appeared on the original ticket
The Amendment Power Under the Provincial Offences Act
The Crown relied on section 34(2) of the Provincial Offences Act, which allows courts to "amend the information or certificate as may be necessary if the matters to be alleged in the proposed amendment are disclosed by the evidence taken at the trial." The Crown argued that since the officer testified the actual speed was 147 km/h, the amendment simply made the certificate conform to the evidence.
Hamilton's lawyer argued this was fundamentally unfair — she had exercised her constitutional right to trial based on the charge of 119 km/h, and was now being "punished" with a higher speed for not pleading guilty. He cited R. v. Dwight Ali (1993), where Justice Allan ruled that amendments which significantly change the consequences for an accused person should not be permitted.
The Crown countered that Hamilton suffered no prejudice because: (1) the fine remained the same, (2) there's little defence available to radar speeding charges once you verify the equipment works properly, and (3) the defence would not have been conducted differently if the original charge had been 147 km/h.
The Court's Analysis
Justice Fontana reserved judgment to consider whether the amendment was properly granted. The case turned on the fundamental question of prejudice — not what the amendment does to the charge, but what effect it has on the accused person's ability to defend themselves. The court had to weigh whether Hamilton had "a full opportunity to meet all issues raised by the charge as amended" and whether her defence would have been conducted any differently.
Key Takeaway
When police give you a break on a ticket, that discretionary reduction should be respected at trial — not reversed through prosecutorial amendments.
This case highlights the tension between an officer's roadside discretion and the Crown's power to amend charges to match evidence. If you receive a reduced charge and choose to fight it, be prepared that the Crown may seek to restore the original, higher reading if their evidence supports it.
2008 ONCJ 714
Ontario Court of Justice — Justice of the Peace Kenneth W. Dechert | June 18, 2008
Background
On October 1, 2006, around 6:00 p.m., Reginald Johnson was driving his green Dodge Caravan westbound on Upper Middle Road in Oakville when he made a left turn onto Postmaster Drive. According to witness Luis Garcia, who was behind Johnson in the left turn lane, Johnson's van turned directly in front of an eastbound black car driven by Arthur Garcia. Arthur had to swerve left to avoid collision, lost control, skidded across both eastbound lanes, mounted the curb, and ended up on a grassy hill facing west — his vehicle traveling over 200 feet from the point of impact.
Luis Garcia claimed he followed the green van "all the way home" without ever losing sight of it, eventually confronting Johnson at his son's residence. Johnson was charged under section 142(1) of the Highway Traffic Act for "Turn-Not in Safety" — essentially making a turn without ensuring it could be completed safely.
Issues
Did the prosecution prove beyond a reasonable doubt that Johnson was the driver who made the unsafe turn?
Was Luis Garcia's identification evidence reliable enough to establish Johnson's guilt?
The Identification Problem
The entire case hinged on Luis Garcia's testimony that he continuously observed the same green van from the intersection to Johnson's residence. But Justice Dechert found major credibility problems with this claim. Garcia testified that after the collision, he remained stopped in the intersection watching Arthur's vehicle slide across the roadway and up the hill — a process taking several seconds. Then he made his own left turn, stopped on Postmaster Drive, and had a conversation with Arthur Garcia who was walking from his disabled vehicle.
The judge found it "exaggerated and overstated" that Garcia could maintain visual contact with the suspect van while simultaneously watching Arthur's dramatic crash sequence and then stopping to chat with him. Garcia couldn't provide the van's license plate, make, or model year — only describing it as a "greenish mini-van." Arthur Garcia's testimony contradicted Luis's version about whether Luis got out of his vehicle during their conversation, further undermining Luis's credibility.
Applying the Supreme Court's test from R. v. W.(D.), Justice Dechert found that while he couldn't fully believe Johnson's denial, the prosecution's identification evidence was too weak to prove guilt beyond a reasonable doubt when considered alongside Johnson's testimony.
Key Takeaway
Eyewitness identification must be continuous and credible — gaps in observation can destroy the prosecution's case entirely.
Even when a witness believes they're telling the truth, courts will scrutinize whether their testimony is realistic given the circumstances. If you're defending a case that relies on witness identification, look for breaks in the chain of observation and inconsistencies between witnesses' accounts.
Ontario Court of Justice10 December 2002fail to yield to pedestrian
R. v. Lorenzo
2002 CarswellOnt 5812, [2002] O.J. No. 4850
Ontario Court of Justice — Quon J.P. | December 10, 2002
Background
Armulfo Lorenzo was driving westbound on Eglinton Avenue West in Toronto on January 1, 2002, when his light brown Chevrolet Cavalier struck pedestrian Anton Alpio in a crosswalk. Alpio testified he had a green walk signal and was crossing between the white lines when Lorenzo's vehicle hit him, causing him to roll over the car and suffer injuries to his knee and elbow. However, witness Robert Bavmanber — who was stopped in the left turn lane — testified that the pedestrian control signals were flashing "don't walk" when he saw Alpio run into the intersection.
Lorenzo was charged with failing to yield to a pedestrian under section 140(1)(a) of the Highway Traffic Act. But after the prosecution closed its case, they realized they had a problem: section 140(1)(a) applies to "pedestrian crossovers" (uncontrolled crossings), while the accident happened at a signalized intersection with traffic lights and pedestrian control signals — which falls under section 144(7) instead.
Issues
Can the prosecution amend the certificate to change from section 140(1)(a) to section 144(7) without prejudicing the defendant's defence?
Would allowing the amendment cause an injustice when considering the merits of the case?
The Amendment Test Under Section 34
Under section 34 of the Provincial Offences Act, courts can amend certificates during trial if the evidence supports the proposed amendment. But there's a two-part test: first, has the defendant been misled or prejudiced in their defence? Second, would the amendment cause injustice considering the merits?
Justice Quon found Lorenzo wasn't misled because both sections involve "failing to yield to a pedestrian" — the core substance was identical. Lorenzo had just struck a pedestrian and received a ticket for failing to yield; no reasonable person would be confused about what they were charged with, regardless of the specific section number. The court noted that the Provincial Offences Act emphasizes "substance over form" and includes a strong bias toward allowing amendments.
More importantly, section 144(7) actually created a higher burden for the prosecution than section 140(1)(a). Under section 144(7), the prosecution had to prove the traffic signals were functioning properly, what they were displaying when Alpio entered the crosswalk, and that the pedestrian was "lawfully" within the crosswalk. Given that witness Bavmanber contradicted Alpio about whether the walk signal was on, this contradiction actually helped Lorenzo's defence.
Key Takeaway
Wrong section numbers on certificates can usually be fixed if the core offence described is the same and the evidence supports the amendment.
The Provincial Offences Act strongly favors substance over technicalities. However, if an amendment would make the prosecution's case easier or create genuine prejudice to your defence strategy, you have grounds to oppose it.
Ontario Superior Court of Justice27 February 2026speeding
Hook: The City fixed the ticket before filing, marched into Superior Court to defend it, and walked out empty-handed — because the officer had no business touching that certificate once it left their hands, and no court above the J.P. was buying the argument otherwise.
R. v. Mahanbir Singh Pawar Ontario Superior Court of Justice — Justice O'Connor April 25, 2007 | Brampton, Ontario | CV-06-00002778-004086
Background
Mahanbir Pawar got pulled over on January 8, 2006 and handed a speeding ticket. He filed a notice of intent to defend. He hired a paralegal firm to represent him. He was ready to fight it.
The problem wasn't with Pawar. The problem was with the ticket itself.
The offence notice Pawar received showed the year of the offence as 2005. The day and month fields had been left blank entirely by the officer. So before filing the certificate with the court, the officer went back to the document — added the day and month, corrected the year — and filed a version that looked complete and correct. The offence notice sitting in Pawar's hands told a completely different story.
When the matter came up for trial, the Justice of the Peace quashed the ticket before Pawar even entered a plea. No record of that proceeding survived — the recording equipment wasn't functioning. The City of Brampton, uninterested in pursuing Pawar personally and having already given him assurances the charge would not be pursued regardless of outcome, went to Superior Court anyway. This, the City told the court, was about the principle. Too many similar charges were being quashed for what it considered minor errors, and it wanted the J.P.'s ruling overturned.
O'Connor J. heard the application. Then he dismissed it.
Issues
Did the Justice of the Peace have jurisdiction to quash the certificate, and if so, was the application properly before the Superior Court?
Does the Provincial Offences Act contemplate or permit an officer to amend a certificate of offence after service of the offence notice but before filing with the court?
Was the certificate — once amended without authority — a valid document at all?
The Legal Framework
The City came in swinging with two arguments. First, that the certificate isn't legally a "certificate of offence" until it's filed with the court, so anything the officer did to it beforehand was fair game — it was just a piece of paper. Second, that even if the amendment was irregular, s. 90 of the POA saves it because a variance between the offence notice and the certificate doesn't affect the validity of the proceeding.
O'Connor J. was not impressed with either position.
On the "piece of paper" argument: the POA makes no distinction between the certificate before and after filing. It doesn't change title upon filing, and there is no authority in the Act to treat the document differently prior to filing. The pre-printed form is the certificate of offence. It is what it is, whether it's in the officer's cruiser or the courthouse file.
On the amendment power: the POA sets out the amendment procedure in ss. 34 and 35 — and that procedure happens in court, with the accused present and able to respond. Regulation 200, s. 15 is unambiguous: amending a certificate of offence shall be dealt with only in court. No exception exists for pre-filing corrections. The Act is silent on changes made before filing — and that silence, the court held, is not permission. It is consistent with the rule that only the court can amend. The notice the defendant walks away with must contain exactly the same information as the certificate. That identity between the two documents is not incidental. It is the protection that exists to prevent alterations from being made to a charging document without the accused's knowledge.
The court also noted the structural problem: ss. 9 and 9.1 of the POA hold default proceedings to a higher standard than contested ones — the certificate must be "complete and regular on its face" before a conviction can be entered in a defendant's absence. A certificate that has been unilaterally altered after service, without court oversight and without the accused's input, is precisely the kind of document those provisions were designed to weed out.
The J.P.'s Decision and What the Superior Court Could Do With It
Without a functioning recording of the proceeding, O'Connor J. could not determine which of two paths the J.P. had taken: he may have quashed using his amendment jurisdiction under s. 34 and found the s. 36 considerations unsatisfied, or he may have concluded the amended document was simply a nullity — no longer a valid certificate at all — because it had been improperly altered in violation of Regulation 200, s. 15.
Either way, the City couldn't get relief. If the J.P. exercised s. 34 jurisdiction, the Superior Court defers to factual determinations, and the City hadn't produced the record needed to demonstrate error. If the J.P. found a nullity — which O'Connor J. identified as the more likely scenario — that conclusion follows directly from the protections the POA builds in against exactly this kind of unilateral alteration. A certificate changed without authority, in a manner the Act does not contemplate, is not a certificate. It is a document that looks complete on its face because the officer made it look that way — and that is the precise mischief the rules exist to prevent.
The City's application was dismissed.
Decision
Application dismissed. The J.P.'s order quashing the certificate stands.
Key Takeaways
Pawar is the Superior Court's definitive rejection of the argument that a certificate of offence is just a piece of paper until it hits the courthouse — and that anything done to it in the meantime is fine because no proceeding has officially started yet.
That argument was dead on arrival. The certificate is the certificate from the moment it's generated. The officer's obligation is to ensure the offence notice and the certificate are identical when they leave their hands. That's not a technicality. It's the architectural foundation of the ticketing system — the defendant receives what the court receives, no more and no less, with no private revisions in between.
Where Pawar goes further than Koza is in the analysis. Koza called the alteration garbage and moved on. Pawar actually works through the statutory scheme — the amendment provisions, the regulations, the default proceeding protections — and arrives at the same place through a reasoned legal framework. The officer had no authority. The alteration was not contemplated by the Act. The resulting document, on the more likely reading, was a nullity.
Wadood would later draw a different line at the Court of Appeal — holding that minor clerical corrections don't doom a prosecution where the defendant was never misled. But Pawar sits on the other side of that line and explains exactly why: the scheme doesn't permit unilateral pre-filing amendments, the defendant is entitled to rely on what they received, and a certificate that has been quietly revised without their knowledge is not the charging document the law requires.
The accused must know what's before the court. When they don't — because someone picked up a pen after service — the certificate has a problem that no curative provision can paper over.
Ontario Superior Court of Justice4 July 2012provincial offence
York (Regional Municipality) v. Burnett
[2012] O.J. No. 3239
Ontario Superior Court of Justice — G.P. DiTomaso J. | July 4, 2012
Background
The Regional Municipality of York issued Gregory Burnett a certificate of offence with the wrong fine amount printed on it. The certificate showed a set fine of $265.00 and total payable of $325.00, but the correct amounts should have been $400.00 and $490.00 respectively. York brought a motion before the Justice of the Peace to amend the certificate under section 34(1)(c) of the Provincial Offences Act, serving notice of this motion by fax to X-Copper, Burnett's legal representative.
The Justice of the Peace dismissed York's motion to amend, ruling that the defect was a "fatal flaw" that couldn't be corrected. York then applied to Superior Court for an order of mandamus with certiorari in aid, seeking to quash the Justice of the Peace's decision and force him to allow the amendment. Burnett's counsel agreed to the relief sought, but raised a last-minute technical objection about service.
Issues
Was service by fax to the defendant's legal representative sufficient under section 87(1) of the Provincial Offences Act?
Should the motion to amend the certificate have been allowed?
The Service Dispute
Burnett's lawyer argued that section 87(1) of the Provincial Offences Act requires service either by personal delivery, mail, or other methods specified in the Act or court rules. Since York served the motion materials by fax to X-Copper rather than personally or by mail to Burnett himself, the service was defective and the entire application should fail.
Justice DiTomaso rejected this argument for several reasons. First, the objection came suspiciously late — it was raised for the first time the day before the Superior Court hearing, despite numerous earlier opportunities. Second, the evidence showed that X-Copper had actually requested and approved fax service to a specific number, and confirmed receiving the documents. Most importantly, the court found that the purpose of service is to give proper notice, and Burnett clearly received notice through his legal representative but chose to "sit on his hands" rather than respond.
The court relied on London (City) v. Erdesz, which emphasized that personal service is ultimately about ensuring the defendant knows about the complaint and has an opportunity to respond. Here, that purpose was clearly achieved through the fax to X-Copper.
Key Takeaway
Courts will look at whether proper notice was actually achieved, not just whether technical service requirements were followed to the letter.
If you receive notice of proceedings through your legal representative and fail to respond or object promptly, you can't later claim defective service as a way to escape the consequences. The court won't reward strategic silence followed by last-minute technical objections.
2009 ONCA 643
Court of Appeal for Ontario — Laskin, Gillese and Rouleau JJ.A. | September 10, 2009
Background
Robert Winlow was caught speeding 30 km/h over the limit on Highway 400 in York Region. The officer used his discretion and wrote the ticket for only 15 km/h over — a common practice that gives drivers a "break" and encourages them to pay the set fine rather than go to trial. The ticket carried a $52.50 total fine. Winlow chose not to pay and requested a trial instead.
At trial, the prosecutor told Winlow that the officer would testify to the actual speed of 30 km/h over, and that they would seek to amend the certificate upward to match the evidence. This would increase the fine from $45 to $90 under the Highway Traffic Act's sliding scale. The prosecutor offered Winlow an adjournment to get legal advice, but he refused and wanted to proceed. The Justice of the Peace refused to allow the amendment, and her decision was upheld on appeal to the Ontario Court of Justice.
Issues
Is the specific rate of speed an essential element of a speeding offence, or just relevant to penalty?
Do courts have discretion to reduce the fines set out in s. 128(14) of the Highway Traffic Act?
Is the practice of "amending up" speeding charges permissible under s. 34 of the Provincial Offences Act?
The "Amending Up" Practice
The Court of Appeal ruled that there's nothing inherently unfair about the common municipal practice of charging at a reduced speed, then seeking to amend upward if the driver goes to trial. The court found this serves two legitimate purposes: giving drivers an incentive to settle out of court (efficiency), and ensuring those who go to trial face consequences matching their actual speed (deterrence).
However, courts must consider the four mandatory factors in s. 34(4) of the POA before granting any amendment: the evidence at trial, circumstances of the case, whether the defendant is misled or prejudiced, and whether the amendment would cause injustice. The court emphasized that "being misled or prejudiced" doesn't mean facing stiffer consequences — it means the defendant's ability to meet the charge would be adversely affected.
The court also clarified that fines under s. 128(14) of the HTA are mandatory calculations with no judicial discretion to reduce them. The phrase "is liable to" creates a fixed penalty regime, not a maximum.
Procedural Fairness Requirements
While the practice is permissible, the court stressed that special care must be taken with self-represented defendants. Prosecutors and justices must ensure defendants understand any proposed amendment, its consequences, and have a reasonable opportunity to make submissions against it. Ideally, notice should be given before trial, and defendants should generally be offered adjournments to seek legal advice.
Key Takeaway
Police can give you a "break" on the ticket, but prosecutors can ask to amend it up to the real speed if you go to trial — and that's legally permissible.
However, you have the right to understand any amendment, make arguments against it, and generally should be offered an adjournment to get legal advice. The court must consider whether granting the amendment would be unfair in your specific circumstances.
