Canon 990

1. Executive power delegated to several persons is presumed to

have been delegated to them individually. 2. When several persons have been delegated individually to transact the same business, the one who first undertakes to deal with it excludes the

others from acting, unless thereafter that person is impeded or

does not wish to proceed further in treating the matter. 3.

When several persons have been delegated to transact some business collegially, all must proceed according to the established

prescription of collegial acts, unless some other provision is

made in their mandate.
