Section 52. The village clerk shall, at the next meeting of the Village Commission, present the petition to the commission which shall proceed to reconsider the ordinance. If within thirty days after the filing of such petition, the ordinance be not repealed or amended as requested, the commission shall provide for submitting the proposed repeal or amendment to a vote of the electors, provided a majority of the committee named in the petition to represent the petitioners shall by writing filed with the village clerk within twenty days after the expiration of the said thirty days, so require. In so doing the Village Commission shall be governed by the provisions of section forty-eight of this charter respecting the time of submission and the manner of voting on ordinances proposed by the Village Commission by petition; excepting that the question of calling a special election for such a purpose shall be determined by the demand and number of signers of the petition requesting the repeal or amendment of such ordinance, which number shall be not less than seventy-five of the qualified electors of the village, and excepting further that the Village Commission may call, and fix the time for a special election for such a purpose, if in its judgement the public interest will be prejudiced by delay.
If, when submitted to a vote of the electors, such repeal or amendment be approved by a majority of those voting thereon, it shall thereupon go into effect as an ordinance of the village; but if any such amendment is clearly separable from the remainder of the ordinance and does not materially affect the other provisions of such ordinance, all sections of the ordinance except that sought to be amended and those dependent thereon shall take effect as though no referendum of any portion of the ordinance had been demanded.
