The appellate process is seldom speedy. Every appellate court in California has a backlog. The most recent statistics for the California court system are for 2018. They show that there were over 5,000 fully-briefed civil appeals pending in the California Courts of Appeal. On average throughout the state, the average time between the filing of the notice of appeal and the disposition of the appeal is 541 days. The fastest court in California disposes of appeals in 420 days, on average, while the slowest takes 803.
Ninety percent of all civil appeals are disposed of within 914 days, on a statewide average. But the slowest courts, in Sacrament and San Jose, take roughly 800 days to dispose of 90% of all of their civil appeals.
