By way of illustration, Coon v. Board of Public Instruction of Okaloosa County [3] is a typical example. In this case, a petition was filed with a local school board to create a tax jurisdiction. At the hearing, it was decided that elections would be held to approve the same thing. However, due to a lack of voter turnout, the election failed. As a result, the school board called a second election. This election was declared successful and the creation of a fiscal territory was approved. However, due to a requirement under some existing laws, the election petition submitted to the school board had to have 10% of the city`s total residents as signatories. But between the filing of the petition and the second election, the city`s population had increased considerably; put the number of petition signatories below the required number. The election was therefore contested for this reason. Meanwhile, the Florida State Legislature has made changes to existing legislation to get the election into effect. The court said the new legislation was a valid healing law, saying the procedural requirement mentioned in the previous law was not required. He stated: «By means of a healing law, the legislature has the power to ratify, validate and confirm acts or procedures that it could have approved from the outset» [4].

Paragraph 686(1)(b)(iii), known as the «healing reserve», allows the Court of Appeal to dismiss an appeal despite finding an error of law in favour of the complainant if there is «no clerical error or miscarriage of justice.» The reservation can be applied if «the result of the study, whatever the error, would necessarily have been the same». [1] Fourth and foremost, the legislative body that enacts the Healing Act must have the power to enact such a law. [9] The Crown must expressly raise the healing reservation itself. It is an error of law if the court relies otherwise. [14] On the other hand, the broad interpretation of section 686(1)(b)(iv) in Esseghaier, supra, was consistent with the purpose of the reservation. Paragraph 686(1)(b)(iv) was enacted to reflect the increasing complexity of criminal proceedings as new common law rules were introduced and new provisions were gradually incorporated into the Criminal Code. With the entry into force of new and complex rules and guidelines, procedural errors have become more common. Without the healing warning of paragraph 686(1)(b)(iv), convictions could regularly be quashed for trivial errors that had little or no effect on the actual outcome.

The Esseghaier verdict thus helped to limit loopholes in the law by reducing the defendants` ability to exploit them on appeal in cases where a well-meaning trial judge had overlooked a technical detail and made a small procedural error. In addition, the second half of paragraph 686(1)(b)(iv) states that a complainant does not need to have suffered a disadvantage as a result of a court`s error, providing a guarantee that limits the recourse powers of the courts of appeal. First, since the main purpose of a healing law is to give legal validity to an act that has taken place in the past, these laws must have retroactive application [5]. A healing law without retroactive application would be ineffective because it would only mean preventing an irregularity in a law from invalidating an otherwise just act for future purposes. But as for an action that has already taken place, it would remain invalid and nullify the purpose for which the correction took place. There are two categories of errors that are subject to reservations:[2] The term reservation also appears in a number of philosophical and political contexts. For example, locke`s reservation is a condition of John Locke`s labor theory of property, which states that while anyone working to convert natural resources into property has a right to that property, he cannot be entitled to such property, «at least when it is sufficient and so good that remains common to others.» In American history, the Wilmot Proviso of 1846 was a failed attempt by Congress to ban slavery in the new territories ceded to the United States after the Mexican-American War – and a catalyst for the Civil War. The reservation reads as follows: «On the express and fundamental condition for the acquisition by the United States of any territory of the Republic of Mexico, under a treaty that may be negotiated between them, and for the use by the executive power of the funds contained in this document, slavery or involuntary servitude shall never exist in any part of that territory, with the exception of offences for which the party is first duly convicted. The Crown has no obligation to «expressly request» the court to rely on the reservation to confirm the conviction.

In «rare cases», the court cannot be limited by the fact that the Crown has not increased the reserve. [4] Moldaver and Brown JJ., speaking for the majority of the Court, discussed whether the trial judge`s error could be saved by the healing warning in paragraph 686(1)(b)(iv) by analyzing jurisdictional and injury issues. The majority argued that the wording should be interpreted broadly in the sense of the reservation and that jurisdiction over the class of offences should therefore refer to the higher courts with jurisdiction over all criminal offences, provincial courts prosecuting summary offences and criminal courts prosecuting offences not listed in section 469 of the Criminal Code. ONCA`s narrow interpretation, which was based on Noureddine, that jurisdiction would be denied in the event of procedural errors in jury selection, was overturned. Since, in the court`s view, the plaintiffs did not suffer any disadvantage as a result of the error made throughout the proceedings, the curative reservation applied, thereby avoiding the trial judge`s error and restoring the convictions. R. v. Esseghaier («Essegbaier») was the first Supreme Court of Canada («the Court») case to determine whether paragraph 686(1)(b)(iv) of the Criminal Code, a healing restriction that allows courts of appeal to correct procedural errors during a trial and uphold convictions, can be used if the errors occur during the jury selection process. In Essegbaier, the Ontario Court of Appeal («ONCA») overturned the defendants` convictions on the basis that paragraph 686(1)(b)(iv) can only apply to trials that have jurisdiction over the offences tried. Because of this limitation, section 686(1)(b)(iv) does not apply if the jury was not properly formed, as the jury partially includes the court`s jurisdiction. Moldaver and Brown JJ. voted in favour of the Majority of the Court in Essegbaier and disagreed with the Court of Appeal`s reasoning and interpreted the reservation broadly, consistent with the Tribunal`s previous decisions on section 686(1)(b)(iv) and the purpose of the reservation.

The Esseghaier decision gives appellate courts more recourse powers that allow them to store convictions if there are small technical errors throughout the process. Another previous decision that paved the way for the decision in Esseghaier was R v. Kakegamic («Kakegamic»). Ruling eleven years before Esseghaier, ONCA had concluded in Kakegamic that the section 686(1)(b)(iv) healing reservation could remedy a procedural error during the jury selection process if the complainant had not suffered any disadvantage as a result of the error. R. v. Sinclair («Sinclair») soon followed ONCA`s decision in Kakegamic. This argument, which originated in Kakegamic and was supported in Sinclair, added credibility to the argument of Moldaver and Brown JJ. in the Esseghaier case.
