Final answer:
Paralegal Ava should cite the ABA Model Rule 3.7 in her brief because it includes explanatory Comments that provide additional clarity and support for her argument.
Step-by-step explanation:
Paralegal Ava, while writing a brief in defense of a lawyer facing disciplinary charges, is considering whether to cite her state's professional conduct rule 3.7 or the ABA Model Rule 3.7. Given that legal English aims to be consistent, complete, valid, and formal to facilitate judicial agreement and that legal briefs are meant to persuade the court without room for ambiguity, she should cite the rule that provides the most clarity and support for her argument. Since the ABA Model Rule includes explanatory Comments that could provide additional context and interpretation to strengthen her argument, Ava's best choice would be to cite the ABA Model Rule 3.7 in her brief in defense of the lawyer.
