Canon 988

1. Ordinary executive power can be delegated either for a

single act or for all cases, unless the law expressly provides

otherwise. 2. Executive power delegated by the Apostolic See

or by the patriarch can be subdelegated, whether for a single act

or for all cases, unless the delegation is granted in view of the

special qualifications of the delegate or unless subdelegation is

expressly prohibited. 3. If executive power delegated by another authority having ordinary power was delegated for all cases,

it can be subdelegated only for individual cases; if, however, it

is delegated for a single act or for a determined act it cannot

be subdelegated except by the expressed grant of the one delegating. 4. No subdelegated power can be again subdelegated validly, unless this has been expressly granted by the one delegating.
