Compensation, allowances and traveling expenses of members

§ 6. Each member of the legislature shall receive for his or her services a like annual salary, to be fixed by law. He or she shall also be reimbursed for his or her actual traveling expenses in going to and returning from the place in which the legislature meets, not more than once each week while the legislature is in session. Senators, when the senate alone is convened in extraordinary session, or when serving as members of the court for the trial of impeachments, and such members of the assembly, not exceeding nine in number, as shall be appointed managers of an impeachment, shall receive an additional per diem allowance, to be fixed by law. Any member, while serving as an officer of his or her house or in any other special capacity therein or directly connected therewith not hereinbefore in this section specified, may also be paid and receive, in addition, any allowance which may be fixed by law for the particular and additional services appertaining to or entailed by such office or special capacity. Neither the salary of any member nor any other allowance so fixed may be increased or diminished during, and with respect to, the term for which he or she shall have been elected, nor shall he or she be paid or receive any other extra compensation. The provisions of this section and laws enacted in compliance therewith shall govern and be exclusively controlling, according to their terms. Members shall continue to receive such salary and additional allowance as heretofore fixed and provided in this section, until changed by law pursuant to this section.
