N1 · 03 Reasons and causes

Says that in a special situation, one can't act otherwise.

Noun or plain clause + とあっては. The first part is a serious condition (a boss's order, a favor), the second part says "I must/cannot". Compare 〜とあれば, which is willing; this one is more "no choice".

Examples

Since it is a request from my benefactor, I cannot refuse.

Given that it is the president's order, I have no choice but to obey.
