Evidence Act 1929

Whenever in any proceedings before justices, in respect of any offence, it is an essential ingredient of the offence that the place (where any fact or matter occurred or was done) should be a public place, an allegation, in the complaint or information, that the place (specified as that in which the fact or matter charged occurred or was done) was a public place, shall be prima facie evidence of that fact, but the court may, if it thinks fit, and at any stage of the proceedings, permit evidence to be called with respect to the said fact.
