Mistrials

From Criminal Law Notebook

General Principles

A mistrial is a remedy where it "is necessary to prevent a miscarriage of justice".[1] A miscarriage can arise where "a trial is unfair, or when the trial has the appearance of unfairness, viewed by a well-informed, reasonable person considering the whole of the circumstances".[2]

A finding of a mistrial is a discretionary power of the trial judge.[3] The Judge must "assess whether there is a real danger that trial fairness has been compromised."[4]

A mistrial will also arise where there is an apprehension of bias.[5]

Pre-Condition to a Mistrial
A declaration of a mistrial "should only be granted as a last resort, in the clearest of cases and where no remedy short of that relief will adequately redress the actual harm occasioned."[6] In a jury trial, a mistrial can only be ordered if the prejudice cannot be remedied by a jury instruction.[7] The decision to grant an application for a mistrial is discretionary.[8]

An appellate court should only intervene where the decision "is so clearly wrong as to amount to an injustice". [9]

For an application for a mistrial the test is "whether the appellant’s ability to make full answer and defence has been impaired." [10]

Other remedies, such as mid-trial instructions, should be considered before a mistrial is granted.[11]

Timing of Application
Courts have jurisdiction to grant a mistrial even after a conviction but before sentencing.[12]

Scheduling of a Re-Trial
A retrial should be scheduled "without further delay". Only a "short period" of delay will be expected. Anything longer may open the possibility of a s. 11(b) Charter delay.[13]

Consequence of Mistrial on Future Matters

Where a mistrial is declared, the rulings on pre-trial motions will generally still apply if the prosecution is re-initiated.[1]

Section 653.1 states:

Mistrial — rulings binding at new trial
653.1 In the case of a mistrial, unless the court is satisfied that it would not be in the interests of justice, rulings relating to the disclosure or admissibility of evidence or the Canadian Charter of Rights and Freedoms that were made during the trial are binding on the parties in any new trial if the rulings are made — or could have been made — before the stage at which the evidence on the merits is presented.
2011, c. 16, s. 14.


CCC

This section is considered a "departure from previous authority from the Supreme Court of Canada to the effect that a trial judge is not bound by interlocutory rulings made at an earlier trial".[2]

Section 653.1 applies to rulings that relate to (1) disclosure; (2) admissibility of evidence; or (3) the Charter.[3]

This presumption to maintaining prior ruling can be rebutted on a balance of probabilities where it is in the "interests of justice".[4]

"Interests of justice" are not limited to the interest of the parties but also the "broad-based societal concerns".[5]

Rebuttal can include considerations such as:[6]

  1. whether any new evidence will be tendered on the proposed rehearing;
  2. whether any new arguments will be advanced on the proposed rehearing and the apparent merit, if any, of those arguments;
  3. the interests of the parties, including any articulable prejudice fostered or perpetuated by the inability to relitigate any issue previously decided;
  4. the public interest in the timely and efficient conduct of criminal trial proceedings and avoidance of unnecessary and duplicative proceedings;
  5. any changes in the legal principles governing the ruling on which relitigation is proposed;
  6. the nature of the evidentiary record on the basis of which the prior ruling was made, as for example, viva voce testimony; agreed statement of facts; transcripts of testimony given elsewhere and any differences in the record proposed for relitigation;
  7. the nature of the issue(s) involved in the prior ruling and proposed relitigation;
  8. the possibility of inconsistent rulings; and
  9. any other circumstances relating to the balance of the subsequent trial proceedings that may have an impact on the continued applicability of the prior rulings.
