There are three good online resources to get information on appellate court cases in Connecticut.
The first resource is a new addition to the state judicial branch website. The public now has access to the case and docket information regarding Supreme Court and Appellate cases. Here is the link. Previously, you could only access trial level cases. This is a great addition to the website and will cut down on trips to the clerk's office to check on the status of a case.
You can get download advanced release opinions from the Supreme Court and Appellate Court. Here is the link.
You can also download copies of some briefs for cases assigned for argument before the Supreme Court. Here is the link. This website is maintained by the Appellate Advocacy Committee of the Connecticut Bar Association. Briefs are typically posted several months after being filed with the court.
