Section 50: Absence of public officers.

In the case of a person employed in the public service of the Federation or of a State who is required to give evidence for any purpose connected with a judicial proceeding, it shall be sufficient to account for his non-attendance at the hearing of the said judicial proceeding if there is produced to the court either a Federal or State Gazette or a telegram, an e-mail or letter purporting to emanate from the head of his department, sufficiently explaining to the satisfaction of the court his apparent default.
