Evidence

(1) If upon any trial a question arises whether any person is an appropriate officer of the Government of Belize, or an officer of customs, or is duly employed for the prevention of smuggling, or is the proper officer, evidence of his having acted as such shall be sufficient, and such person shall not be required to produce his commission or deputation unless sufficient proof is given to the contrary. (2) Every such officer and any person acting in his aid and assistance shall be deemed a competent witness upon the trial of any suit or other proceeding on account of any seizure or penalty as aforesaid, notwithstanding that such officer or other person may be entitled to the whole or any part of such seizure or penalty, or to any reward upon conviction of the penalty charged in such suit or other proceeding.
