A new city policy aimed at preventing the fixing of traffic and parking tickets issued by the Lawrence Police Department by more closely monitoring the procedure for dismissing tickets “has been effective,” according to Lawrence Police Sgt. Trent McKinley.

The policy, which creates a tracking system for attempts by department employees to void or dismiss tickets, was created in the wake of a ticket-fixing scandal last year that led to the dismissal of two Lawrence officers.

According to a report provided to city officials earlier this year, between Aug. 27 — when the policy was implemented — and the end of the year, police officers requested that 16 tickets be dismissed.

Of those, six involved cases already charged in district court, while seven involved some form of equipment or a ticket-writing error.

The remaining three cases involved a ticket written to a U.S. Secret Service vehicle on official business; one given to an unmarked police vehicle; and a ticket given by an officer in training, which was later dismissed because of a lack of evidence.

McKinley declined comment on how requests for dismissal were handled prior to the new policy, citing pending litigation involving the city.

In February, former Sgt. Michael Monroe filed a lawsuit against the police and the city alleging that racial discrimination played a role in his firing in 2012. In the lawsuit, Monroe described several cases where he or another Lawrence officer dismissed tickets for friends and family.
