いかんを問とわずRegardless of how something is or turns out

What it does

The noun identifies a variation that might normally affect a decision. The phrase then removes that variation from consideration, and the following clause gives the rule or action that applies uniformly. Here, 問とわず does not literally mean that nobody asks a question; the whole fixed phrase means “without regard to.”

A rule applied regardless of the result

Choosing the noun

The noun should name a matter whose different possible forms or outcomes could otherwise matter. Typical choices include a reason, purpose, result, content, nationality, or employment status. The sentence then makes clear that the same policy applies in every case.

Close alternatives

いかんにかかわらず and いかんによらず are close formal equivalents; there is no useful sharp difference in meaning to memorize. The main practical distinction is the fixed particle and ending. More general forms such as を問とわず and にかかわらず express “regardless of” with less elevated, less bureaucratic wording.
