Expressio unius est exclusio alterius: statutory omission may imply exclusion but must not produce inconsistency or injustice. Maxim expressio unius est exclusio alterius functions as a rule of exclusion by necessary implication to infer that omissions in a statute exclude unstated rights or procedures, but it is an interpretive aid that must not be applied where it yields inconsistency, injustice, or contradicts clear statutory language; apparent omissions may reflect inadvertence or caution rather than legislative intent.
