42. If questions of fact arise in matters before the council or its committees, which the interests of the municipal corporation require to be investigated by the examination of witnesses on oath or otherwise, or if it also becomes necessary, in the like interest, to institute inquiries into the truth of representations which may be made to the council respecting matters within its jurisdiction, any committee appointed by the council to investigate the same, or to make such inquiry, or the committee before which any such question arises, may issue a summons signed by its chairman requiring any person to appear before such committee, for the purpose of giving evidence touching such question or inquiry, and also, if deemed expedient, to produce any papers or documents in his possession or under his control, bearing upon such question or inquiry, and described in such summons.
If any person so summoned neglects or refuses to appear at the time and place appointed by such summons, or if, appearing, he refuses to be examined on oath touching the said inquiry, or to obey any order to produce papers or documents mentioned in such summons, so far as he is able to do so, a return of the issue and service of the summons and of such default or refusal may be made to the mayor, who may thereupon compel him to answer all lawful questions by such means as are used for such purposes in the ordinary courts of civil jurisdiction in Québec.
The chairman of any committee of the council may administer the oath to the witness.
