If the electors approve the establishment of a community court at the primary election in a municipal election year, the first judges of the court shall be elected at that municipal election. The nominees for election shall be determined in the same manner as is then provided for by law in the case of substitution of nominees where a nominee for a judge of the court of common pleas has died subsequent to a primary election. If the electors approve the establishment of a community court at the primary election in a general election year, the first judges of the court shall be nominated at the primary election preceding the next following municipal election and shall be elected at such municipal election.
