The following answer was returned:
*198 To the Honorable Senate:
The undersigned Justices of the Supreme Court submit the following answers to the inquiries contained in your resolution adopted May 19, 1971 and filed with this court on May 20, 1971.
The following questions are contained in your resolution:
“1. Can the General Court enact a statute by a simple majority vote, which authorizes the General Court to prescribe the time and mode for submitting constitutional amendments to the voters?
“2. In establishing the time and mode for submitting an amendment to the voters, is a simple majority vote of both houses sufficient or is a three-fifths vote of each house required?
The attached bill makes it clear that the questions relate solely to amendments to the Constitution proposed by the General Court rather than by a constitutional convention. The provision permitting proposals for constitutional amendments by the General Court was added to our State Constitution in 1964 and reads as follows: “The senate and house of representatives, voting separately, may propose amendments by a three-fifths vote of the entire membership of each house at any session. ” N.H. CONST., pt. II, art. 100( a). The General Court must comply with the mandatory provisions of pt. II, art. 100( a) in order to adopt a proposed amendment. Bednar v. King, 110 N.H. 475, 272 A.2d 616 (1970); Leach v. Brown, 167 Ohio St. 1, 145 N.E.2d 525 (1957).
Neither pt. II, art. 100( a) nor any other provision of our Constitution prescribes the time and mode of submission of proposed amendments to the Constitution. Where the Constitution has failed to specify the mechanics of carrying out a constitutional mandate the general legislative power of the General Court authorizes it to do so by statute. Opinion of the Justices, 76 N.H. 586, 79 A. 29 (1911); see RSA ch. 68-A.
A constitutional convention has no general legislative power but it has been considered to possess limited power by implication when “necessary for the business of preparing questions of revision and submitting them to the people. ” Opinion of the Justices, 76 N.H. 612, 613, 85 A. 781, 782 (1889); Opinion of the Justices, 102 N.H. 565, 163 A.2d 1 (1960). An act of the legislature prescribing the time and mode of submitting proposed constitutional amendments is a statute properly enacted under the general legislative power of the General Court. N.H. CONST., *199pt. II, art. 5; 16 C.J.S. Constitutional Law 5. 9b(3) (1956); 16 Am. Jur. 2d Constitutional Law s. 36 (1964). Enacted under the general legislative power rather than the special authority of pt. II, art. 100 ( a ) there is no requirement that the three-fifths mandate of that provision be complied with.
We answer the first question, yes, and the answer to the second question is that a simple majority vote of both houses is sufficient in establishing the time and mode for submitting an amendment to the voters.
