The Stockton City Council ruled 6 to 0 that Mayor Randall Ronk violated the City Charter by falsifying travel vouchers. The mayor was not present as the council found that he violated the Charter seven times by making $3,100 in travel claims for meetings he failed to attend. The council set a hearing July 3 to decide what to do about its findings. The city attorney’s office staff was ordered to investigate legal alternatives. Vice Mayor Jim Parkinson suggested that options might range from requiring that Ronk repay the money to suspending him for a period of time to removing him as mayor. Ronk, 30, was recently acquitted in San Joaquin County Superior Court of 10 felony counts of defrauding the city.
