The contract is watertight; the other side couldn’t find a single fault.
Tone: positive (praise).
Usage and origin
懈 is slackness or a gap, so there is no opening to strike at. Said of arguments, defences, plans and performances: 论证无懈可击. Compare 天衣无缝 (seamless), which stresses perfect craft rather than resistance to attack.
