Attorney Files Contract Claim

The court accepted the filing because the contentions tracked existing doctrine without needing any extension.

Lucas Lee faced a theft prosecution. His counsel contested every element at trial even though the facts were undisputed. The defense was proper because the attorney could require the state to prove each element under current doctrine.

Common questions
Frequently Asked
4
How does lex lata differ from an argument to change the law?+
Lex lata consists of the statutes, precedents, and rules already in force. A lawyer may rely on it directly. An argument to extend or reverse that body of law must be identified as nonfrivolous and presented separately under the certification rules.
When may a lawyer rely solely on lex lata in a pleading?+
A lawyer may rely solely on lex lata when the claims or contentions are warranted by existing statutes or binding precedent. No separate nonfrivolous extension argument is required in that situation.
Does a discovery certification require support from lex lata?+
Yes. The signer must certify that the response is consistent with the rules and warranted by existing law or a nonfrivolous argument for change. A bare assertion without reasonable inquiry into current standards violates the rule.
Can a criminal defense lawyer force the state to prove every element even when the facts favor conviction?+
Yes. The lawyer may defend by requiring the prosecution to establish each element under current doctrine. This remains true even if the defense does not contest the underlying facts.
