Regulation 20 Evidence of analysis

In England and Wales in any proceedings under these Regulations the production by one of the parties of a document purporting to be a certificate under regulation 13(3), or of a document supplied to him by the other party as being a copy of such a certificate, shall be sufficient evidence of the facts stated therein, unless, in the first mentioned case, the other party requires that the analyst shall be called as a witness.

In Scotland in any proceedings under these Regulations the production by one of the parties of a document purporting to be a certificate under regulation 13(3), or of a document supplied to him by the other party as being a copy of such a certificate, shall be sufficient evidence of the facts stated therein, unless, in the first mentioned case, the other party requires that the analyst shall be called as a witness, and in that event the evidence of the analyst shall be sufficient evidence of the aforesaid facts.

In any such proceedings if a person charged, or in Scotland an accused, intends to produce a certificate of a public analyst, or under paragraph (1) or (2) above to require that the analyst shall be called as a witness, notice of his intention, together, in the first mentioned case, with a copy of the certificate, shall be given to the other party at least three clear days before the hearing or trial, and, if this requirement is not complied with, the court may, if it thinks fit, adjourn the hearing or trial on such terms as it thinks proper.
