In which of the following case benefit of Section 5 of the Limitation Act, 1963 is not available?

Applications under Order XXI of the Code of Civil Procedure are expressly excluded from section 5 of the Limitation Act, 1963.

Order XXI concerns execution of decrees and orders, and its applications cannot use this general section 5 power merely by showing sufficient cause.
