The following rules shall govern the council when considering proposals for amendment of ordinances and resolutions:
(1) All amendments to resolutions and ordinances must be reduced to writing before they may be considered to be properly before the council;
(2) An amendment must be germane to the proposition to which it is to apply;
(3) A primary amendment may be amended, but a secondary amendment (an amendment to an amendment) may not be amended;
(4) When adopted, an amendment merely modifies the proposition or question to which it applies and the question before the council is then the consideration of the proposition or question as amended;
(5) An amendment once rejected may not be moved again in the same form in the same meeting of the council without first reconsidering the vote by which the amendment was defeated. (Ord. 79-97 § 2 (part), 1979).
