Local Government (Scotland) Act 1947

43 Where an order is made for the production by the county clerk or town clerk of any document in his possession relating to any specified election, the production by that clerk or his agent of the document ordered in such manner as may be directed by the order shall be conclusive evidence that the document so produced relates to the specified election; and any endorsement appearing on any packet of ballot papers produced by that clerk or his agent shall be prima facie evidence of those papers being what they are stated to be by the endorsement. The production from proper custody of a ballot paper purporting to have been used at any election and of a counterfoil marked with the same printed number and having a number marked thereon in writing shall be prima facie evidence that the person who voted by that ballot paper was the person who at the time of that election had affixed to his name in the register of electors at that, election the same number as the number written on that counterfoil.
