Section 4. General Law.
   The term "general law" used in this Charter means the law of Ohio together with amendments thereof existing at the time it is to be applied. If this Charter specifies general law only shall control and said general law is repealed and no substitute provision enacted, then the Council may by ordinance establish the rule to be followed.
XX.    CHARTER AMENDMENTS
   This Charter is intended to be flexible and to be changed to meet changing conditions as the Municipality develops, in order that the best interests of those who live and work here may continue to be served. Amendments shall be submitted to the electors by affirmative vote of five members of Council, or shall be submitted upon petition signed by ten percent of electors not less than seventy-five days prior to the date of an election at which such amendments are to be voted on. If any such amendment is approved by a majority of the electors voting thereon, it shall become a part of this Charter.
   Council may establish a Charter Revision Committee which shall consist of five electors selected by the Council to overlapping five year terms. Any vacancy on the committee may be filled in the same manner but shall be for the balance of the remaining term. It shall be the duty of the Charter Revision Committee to advise the voters and Council as to any amendments or improvements that shall be desirable and proper to keep this Charter fitted to the needs of the Municipality as such needs develop in the future. Whenever the Committee has recommendations, it shall submit a written report to the Council, stating suggestions for changes to be submitted to the electors.
