pleading in the alternative

To initiate a law suit, a pleading had to be drafted to meet myriad technical requirements: correctly categorizing the case into the correct legal pigeonhole (pleading in the alternative was not permitted), and using specific "magic words" encrusted over the centuries.

Because pleading in the alternative is generally permitted in criminal cases, a defendant may claim to have not committed the crime itself, but at the same time may claim that if the defendant had committed the crime, the act was excused for a reason such as insanity or intoxication, or was justified due to provocation or self-defense.
