Canon 137. §1 Ordinary executive power can be delegated either for an individual case or for all cases, unless the law expressly provides otherwise.

§2 Executive power delegated by the Apostolic See can be subdelegated, either for an individual case or for all cases, unless the delegation was deliberately given to the individual alone, or unless subdelegation was expressly prohibited.

§3 Executive power delegated by another authority having ordinary power, if delegated for all cases, can be subdelegated only for individual cases; if delegated for a determinate act or acts, it cannot be subdelegated, except by the express grant of the person delegating.

§4 No subdelegated power can again be subdelegated, unless this was expressly granted by the person delegating.

§1. Potestas exsecutiva ordinaria delegari potest tum ad actum tum ad universitatem casuum, nisi aliud iure expresse caveatur.

§2. Potestas exsecutiva ab Apostolica Sede delegata subdelegari potest sive ad actum sive ad universitatem casuum, nisi electa fuerit industria personae aut subdelegatio fuerit expresse prohibita.

§3. Potestas exsecutiva delegata ab alia auctoritate potestatem ordinariam habente, si ad universitatem casuum delegata sit, in singulis tantum casibus subdelegari potest; si vero ad actum aut ad actus determinatos delegata sit, subdelegari nequit, nisi de expressa delegantis concessione.

§4. Nulla potestas subdelegata iterum subdelegari potest, nisi id expresse a delegante concessum fuerit.
