Cap. 16 Art. 2145Rights which cannot be exercised but seldom.

(1) The provisions of the last preceding article shall also apply in the case of a right, even if ecclesiastical, which cannot be exercised but seldom.

(2) In any such case, however, the party pleading prescription must, besides the lapse of forty years, prove also that, within such period, there were at least three occasions on which such right could have been exercised, and that on each occasion he exercised such right, or, as the case may be, that the party to whom such right was competent failed on each occasion to exercise it.
