57. Evidence of precise description of liquor not necessary
In any prosecution for an offence with respect to liquor, it shall not be necessary that any witness should depose directly to the precise description of the liquor with respect to which the offence has been committed or to the precise consideration thereof or to the fact of the offence having been committed with his or her participation or to his or her own personal or certain knowledge, but as soon as it appears to the court that the circumstances sufficiently establish the offence complained of, the court shall put the defendant on his or her defence and in default of such evidence being rebutted, shall convict the defendant accordingly.
