The passage or adoption of every ordinance, and every resolution or order to enter a contract shall be by roll call of the council with the yea or nay of each being recorded, and to pass or adopt any ordinance or any such resolution or order, a majority of the council shall be required.
Ordinances shall be read on three (3) different days, two (2) readings of which may be by title only and one (1) reading of which shall be in full, unless one half (1/2) plus one (1) of the members of the full council shall dispense with the rule. In preparation, passage and publication, ordinances shall contain no subject which shall not be clearly expressed in the title, and no ordinance or section thereof shall be revised or amended unless all ordinances, which are intended to amend existing ordinances, shall have the words which are added to such ordinance underlined; when the amendment is to strike out or repeal any part of an existing ordinance, the letter, figure, word or words stricken or repealed shall be printed with a line through such letter, figure, word or words in the printed bill to indicate the part stricken or repealed. Provided, however, that when an ordinance includes or consists of the repeal of an entire section or chapter, it shall not be necessary to print such repealed section or chapter.
All ordinances may be proved by a certificate of the clerk under the seal of the city and when printed or published individually in book or pamphlet form by authority of the city, shall be read and received in evidence in all courts and places without further proof.
