Canon 1491

1. Laws passed by the supreme authority of the Church are

binding everywhere on all those for whom they were enacted,

unless they were for a particular territory; other laws have

force only in the territory where the authority that promulgated

them exercises power of governance, unless otherwise provided by

law or is clear from the nature of the matter. 2. Without

prejudice to the provisions of 3, n. 1, laws passed for a particular territory bind those for whom they were enacted and who

have a domicile or quasi-domicile in that territory and are actually residing in it. 3. Travelers: (1) are not bound by

the particular laws of their own territory as long as they are

absent from it, unless their violation would cause harm in their

own territory or unless the laws are personal ones; (2) are not

bound by the particular laws of the territory in which they are

present with the exception of those laws which provide for public

order, which determine the formalities of legal actions, or which

deal with immovable goods situated in that territory; (3) are

bound, however, by the common law and the particular law of their

own Church sui iuris, even if the latter is not in force in their

own territory; but they are not bound by the same laws if these

do not bind in the place where they are present. 4. Transients

are bound by all the laws which are in force in the place where

they are present.
