EXPLANATION / SCOPE

The burden of proof lies on the party asserting the affirmative of an issue. This applies to both plaintiffs and defendants. The principle applies to civil proceedings. Whoever substantially asserts the affirmative bears the burden. The rule is fundamental to burden of proof law. The court identifies the party making the positive assertion.
