Cumulative Error Analysis Law and Legal Definition

Cumulative error analysis refers to the scrutiny made by an appellate court of all the individual harmless errors made in a trial to find out if it has the cumulative effect of prejudicing the outcome. If the outcome is positive then all the harmless errors taken together may amount to reversible error. A reversible error is one which affects a party's substantive rights or the outcome of a case, and is a ground for reversal if the party properly objected.
