Добрый вечер,
просьба помочь перевести:
ruling and/or the controlling principle of law or equity leading to the ruling
в контексте:

if the ruling and/or the controlling principle of law or equity leading to the ruling is subsequently overruled, modified, or amended by legislative, judicial, or administrative action, then the provision(s) in question as originally set forth in the Agreement shall be deemed valid and enforceable to the maximum extent permitted by the new controlling principal of law or equity.
Спасибо!
