When does a procedural mistake invalidate an entire trial?

Not every error in a criminal trial should overturn a conviction. How do different legal systems decide which procedural mistakes are fatal and which can be ignored?

Most systems distinguish absolute nullities—defects so fundamental they void the proceeding regardless of harm (lack of jurisdiction, no impartial judge)—from relative nullities—errors that require the defendant to show actual prejudice (e.g., late notice of hearing). The global trend is away from automatic, formalistic nullification. Courts increasingly ask: Did the error actually impair the fairness of the trial? If not, the conviction stands. The principle is moving from "perfection or void" to "fair enough, despite imperfection."
