§ 61. Subcommittees. Whenever any committee of either house or a joint
committee of both houses of the legislature shall be required to make an
inquiry or investigation, such committee may appoint a subcommittee of
not less than three of its own members to make such inquiry or
investigation, and to take testimony in relation thereto; and such
committee or subcommittee and the chairman thereof shall respectively
have all the powers and authority, which are conferred by law upon any
committee which is authorized to send for persons or papers, or upon the
chairman thereof. No subcommittee shall have the power to take testimony
at a private hearing or at a public hearing unless at least two of its
members are present at such hearing.
