Subject to the exceptions which follow, (1) ordinances may be enacted, amended or repealed by the affirmative vote of not less than four Councilmen, (2) no ordinance shall be finally enacted by the Council until after publication of the proceedings, or summary thereof, of the meeting at which it is introduced, and (3) the effective date of all ordinances shall be prescribed therein but the effective date shall not be earlier than twenty days after the enactment nor before publication thereof. It is provided however, that an ordinance which is declared therein to be immediately necessary for the preservation of the public peace, health or safety may be enacted before publication of the proceeding of the meeting at which it is introduced, or may be given earlier effect than twenty days after its enactment, or both, by the affirmative vote of not less than five Councilmen if six or seven Councilmen are present at the meeting at which it is enacted or by the affirmative vote of not less than four Councilmen if four or five Councilmen are present at the meeting at which it is enacted. In case an ordinance is given effect earlier than twenty days after its enactment, the requirements for publication before such ordinance becomes operative may be met by posting copies thereof in conspicuous locations in ten public places in the city; and the Clerk shall, immediately after such posting, enter in the Ordinance Book under the record of the ordinance a certificate under his hand stating the time and place of such publication by posting, which certificate shall be prima facie evidence of such publication by posting of the ordinance. Such ordinance shall also thereafter be published in accordance with Section 4.9 of this charter, but not as a requirement for the effectiveness thereof.
Unless by the affirmative vote of four Councilmen, no office shall be created or abolished, no tax or assessment shall be imposed, no street, alley or public ground shall be vacated, no real estate, or any interest therein shall be sold or disposed of, no action shall be taken to condemn private property for public use, no money shall be appropriated, nor shall any vote of the Council be reconsidered or rescinded.
No ordinances shall be revised, altered or amended by reference to the title only, but the section or sections of the ordinance revised, altered or amended shall be reenacted and published. However, an ordinance or section thereof may be repealed by reference to its title and ordinance or code number only.
