Canon 992

1. Delegated power ceases by fulfillment of the mandate, by the

lapse of the time or by the completion of the number of cases for

which it was granted, by cessation of the final cause of the delegation, by the revocation of the one delegating directly communicated to the delegate, as well as by the resignation of the

delegate made known to and accepted by the one delegating; it

does not cease, however, by the expiration of the authority of

the one delegating, unless this is clear from clauses appended to

the grant. 2. An act of delegated power which is exercised

only for the internal forum and which is placed inadvertently

after the lapse of time or after the completion of case for which

is was granted, is valid.
