The Latin maxim "ut res magis valeat quam pereat", means

Where alternative constructions are equally open that alternative is to be chosen which will be consistent with the smooth working of the system which the statute purports to be regulating and other alternative is to be rejected.

Words suspectable of analogous meaning if used together are given cogent meaning.

If the words clearly omit certain cases the words cannot be strained to include them.

Expression used many times must be given same meaning every time.
