In any prosecution for neglect to comply with the provisions of Part IX. of the Health Act 1890, sec. 214 of the Act renders it necessary for the prosecution, in order to launch a prim facie case, only to prove that the deputy-registrar or any other officer has given or sent, by post or otherwise, notice of the requirement of such part; and either sec. 214 of the Act or else the maxim "omnia prsumuntur rite esse acta" makes it unnecessary for the prosecution to prove that the Governor in Council has by proclamation divided Victoria into districts, and has appointed a place or places in a district, in which the child or the defendant is resident, for the performance of vaccination, within the terms of sec. 191 of the Act, or that a public vaccinator has been appointed for the district in which the child or the defendant is resident.
