compare the relevant State G professional conduct rule with the corresponding rule in State Y. If they are the same, then she may be able to use case she found.

only look for cases from her state because other state case law is irrelevant

compare the State G professional conduct rule with the ABA Model Rule. If State G has changed the rule, then it is invalid.

check for other cases, because the case she found is useless.
