Sec. 102. 

All rules made as hereinbefore provided, and all changes therein, shall be printed for distribution by said board. By publication in the official paper the board shall give notice of the place or places where said rules may be obtained, and in such publication shall be specified the date, not less than thirty days subsequent to the date of such publication, when said rules shall go into operation.  (Added, 1925.)

Where the genius of a city charter is such that rules created by the Board of Civil Service Commissioners are to be followed with the same strict conformity as are charter provisions, there is no justification in authority or in reason to hold that the board may, at any time, arbitrarily, and without following the forms prescribed by the Charter, suspend a rule in order to accommodate one claiming to be aggrieved.
