He said the new rules have not had an effect on the number of appeals coming in, but legislative reforms have led to a decrease in the number of medical malpractice lawsuits and workers' compensation claims.
In 1999, workers' compensation claims made up 65 percent of the state Supreme Court's caseload. Last year, worker's comp cases made up 35 percent of the court's docket.
Abuse and neglect cases took up 15 percent of the court's caseload, with 195 cases. There were 223 torts, contracts and real property appeals, making up 17 percent of the Supreme Court's docket. There were 166 criminal felony cases and nine criminal misdemeanor cases, making up around 14 percent of the caseload.
The rest of the court's time was spent on civil cases, domestic violence, administrative and family court cases.
Prior to 2010, the high court's appellate rules had not been revised for more than 35 years.
Perry said the state had a "sloppy" appellate process, where lawyers were allowed to submit appeals simply by passing all documents from lower courts' rulings up to the state Supreme Court.
"We basically let the lawyers decide which cases were appropriate for oral argument," he said.
Now, attorneys must only submit information relevant to their clients' Supreme Court appeal.
Perry said the court experienced a slight backlog of cases after implementing the new rules but are now have just as many cases going out as there are coming in.
"It's taken a number of years for us to catch up with ourselves," he said.
