Cap. 9 Art. 638Production of fullest evidence available. Single witness sufficient.

(1) In general, care must be taken to produce the fullest and most satisfactory proof available, and not to omit the production of any important witness.

(2) Nevertheless, in all cases, the testimony of one witness if believed by those who have to judge of the fact shall be sufficient to constitute proof thereof, in as full and ample a manner as if the fact had been proved by two or more witnesses.
