Article 64. Immediately after their election, the Representatives shall be furnished with certificates of election, subscribed in the rural districts by the magistracy, in the towns by the chief magistrate, and in both cases by several electors, as evidence that they have been elected in the manner prescribed in the Constitution. The validity of these credentials shall be passed upon by the Storthing. Article 65. Each Representative shall be entitled to compensation, from the State Treasury, for expenses of travel to and from the Storthing, and for subsistence during attendance. Article 66. Representatives shall, except when apprehended in public offences, be privileged from arrest during their attendance at the Storthing, and in going to and returning from the same; and they shall not be answerable, outside of the sessions of the Storthing, for the expression of their views therein; but every Representative shall conform to the established rules of procedure. Article 67. The Representatives, elected in the manner aforesaid, shall constitute the Storthing of the Kingdom of Norway. Article 68. The Storthing shall, as a rule, convene on the first week-day in the month of February in each year, at the capital of the Kingdom, except when the King, on account of extraordinary circumstances, such as hostile invasion or contagious disease, shall designate another town in the realm therefor. Timely notice of such designation shall, in such case, be published. Article 89. The King may, on extraordinary occasions, convene the Storthing at other than the usual time. In such case the King shall issue a proclamation, which shall be read in all the churches of the Episcopal towns at least fourteen days before the members of the Storthing shall assemble at the place prescribed. Article 70. Such special Storthing may be adjourned by the King at his pleasure. Article 71. The members of the Storthing shall serve as such for three successive years, as well at all special, as at all regular, sessions that may in the meantime be held. Article 72. If a special Storthing be in session at the time a regular Storthing convenes, the former shall adjourn before the latter assembles. Article 73. The Storthing shall select from its members one-fourth who shall constitute the Lagthing; the other three-fourths shall constitute the Odelsthing. The selection shall be made at the first regular Storthing which convenes after an election, and thereafter the Lagthing shall remain unchanged in all Storthings assembled after the same election, except in cases of vacancy, which shall be filled by special election. Each Thing shall hold its sessions separately, and appoint its own President and Secretary. Neither Thing shall be in session unless two-thirds of its members are present.
