How to say "constitutional" in Japanese

• 合憲的ごうけんてき
  na-adjectiveThe legal sense: conforming to, or valid under, a constitution, as opposed to unconstitutional. Used when judging whether a law or official action is constitutional; a less common rendering of this sense.
• 憲法上けんぽうじょう
  no-adjectiveAlso the legal sense, but meaning 'under the constitution': matters viewed from the standpoint of what the constitution provides or permits—constitutional questions, rights, or limits; also a less common choice.
• 体質的たいしつてき
  na-adjectiveThe non-legal sense: 'constitutional' as in innate bodily or mental makeup—a constitutional disposition or weakness. About inherent character, structure, or nature, not the legal constitution; a less common match for the English word.

Choose 合憲的 or 憲法上 for the legal sense of 'constitutional'—the former judging conformity to a constitution, the latter framing matters as arising under it—and 体質的 for inherent physical or mental makeup.
