When to use it

Means "regardless of A." The rule or result stays the same however A turns out: the reason, the result, nationality, age. Example: 理由りゆうのいかんを問とわず、返金へんきんできません (no refunds for any reason). Typical of rules, terms of service, application guidelines, store notices and official announcements.

Nuance

Very formal and written, often found in contracts and signs. The three forms mean the same; いかんを問とわず is the most common in notices, and いかんにかかわらず is slightly softer. The main clause is usually a rule, condition or policy.

Compare

にかかわらず is the plain version and attaches to pairs or ranges: 年齢ねんれいにかかわらず, 晴雨せいうにかかわらず. を問とわず: 経験けいけんを問とわず. The いかん forms are more formal. The opposite idea is いかんでは ("depending on"), where the result does change: 結果けっかいかんでは中止ちゅうし.

Tip: Add の after a noun phrase like 理由りゆう or 結果けっか: 理由りゆうのいかんを問とわず is the textbook phrase to memorize.
