The appellant physician in a medical malpractice action appealed a motion judge's decision denying leave to file late-served causation and damages expert reports under Rule 53.08.

The motion judge had applied a strict conjunctive test, finding no reasonable explanation for the delay despite acknowledging a lack of prejudice.

The Divisional Court allowed the appeal, holding that the motion judge erred by failing to apply a balanced approach that considers the overall interests of justice, as established in recent jurisprudence.

The Court found that the delay was not tactical, did not prejudice the respondents or delay the trial, and that denying leave would disproportionately prejudice the appellant's ability to defend the action on its merits.

The defendant physician in a medical malpractice action sought an extension under rr. 53.03(4) and 53.08(1) of the Rules of Civil Procedure to serve three late expert reports.

The court granted the motion with respect to one report, finding that the unexpected death of the originally retained expert constituted a reasonable explanation for the delay.

However, the court denied the motion for the remaining two reports, holding that trial counsel's admitted inattentiveness to the file and deliberate choice to prioritize other matters did not constitute a reasonable explanation, and that the conjunctive test under the amended r. 53.08(1) required dismissal absent satisfaction of that threshold.
