To appeal to the Connecticut Supreme Court, you generally file a petition for certification within twenty days after the Appellate Court releases its decision, and at least three justices must vote to take the case. A small category of cases skips the Appellate Court entirely and reaches the Supreme Court by right, including serious felony convictions, constitutional rulings, and election disputes. Everything else depends on convincing the justices that your case raises a legal question worth their attention.
Cases That Go Straight to the Supreme Court
Connecticut General Statutes § 51-199 lists the matters that bypass the Appellate Court. If your case falls into one of these categories, you have a right to Supreme Court review rather than a request for it. The main ones:
- A Superior Court ruling that a state statute or a provision of the state constitution is invalid.
- Criminal appeals involving a Class A felony or any felony where the maximum possible sentence exceeds twenty years, including persistent-offender enhancements.
- Challenges to election or primary results brought under the election statutes.
- Appeals from reprimands or censures of probate judges, and matters involving the removal or suspension of any judge.
- Reapportionment matters where the Supreme Court has original jurisdiction under Article XVI of the state constitution when the reapportionment commission misses its deadline.
If your case is not on this list, your route runs through the Appellate Court first, and then through certification.1Justia. Connecticut Code 51-199 – Jurisdiction
Petitioning for Certification After an Appellate Court Decision
Most appeals reach the Supreme Court through certification. After the Appellate Court issues a final decision, the losing party can petition the Supreme Court to review it. There is no right to this review. The court selects only the cases it considers most significant, typically those raising unresolved legal questions or issues of broad public importance.2Justia. Connecticut Code 51-197f – Further Review by Certification Only
Petitions do better when they identify a real conflict: different Appellate Court panels reaching inconsistent conclusions on the same legal issue, or an Appellate Court ruling that appears to depart from established Supreme Court precedent. The panel that decided the case can also petition the Supreme Court to review its own decision, which sometimes happens when the judges themselves see a question the high court should resolve.
The Twenty-Day Deadline
Timing is unforgiving. A petition for certification must be filed within twenty days of the date the Appellate Court officially releases its decision. If a party files a timely motion for reconsideration with the Appellate Court, the twenty-day window restarts from the date the Appellate Court rules on that motion. Any other party harmed by the Appellate Court’s decision can file a cross-petition within ten days after the original petition is filed.3Connecticut State Library.

What the Petition Must Contain
A petition for certification is not a full merits brief. It is a focused request explaining why the Supreme Court should get involved at all. The petition must set out the specific questions of law you want the court to address and explain why those questions matter enough for the state’s highest court to weigh in. You also need a statement of prior proceedings tracing the case through the Superior Court and Appellate Court, along with a copy of the Appellate Court’s decision.
Frame the questions carefully. Too narrow, and the case looks like a fact-bound dispute the court has no reason to take. Too broad, and the petition looks unfocused. The strongest petitions tie the legal question to a gap or conflict in existing case law that affects people beyond the parties in the case.
Filing Procedures and Costs
Attorneys file petitions electronically through the Connecticut E-Services platform. Self-represented parties can use the electronic system or follow paper filing procedures. The entry fee for filing an appeal or petition with the Supreme Court is $250, with fee waivers available for parties who qualify based on financial need.4Justia. Connecticut Code 52-259 – Court Fees You must serve copies on the opposing parties and provide proof of that service.
Expect substantial costs beyond the filing fee. Appellate attorneys typically charge between roughly $140 and $600 or more per hour, and a full certification proceeding through briefing and oral argument involves many hours of work. Official trial transcripts, often required for the appellate record, run several dollars per page and add up quickly in cases with lengthy proceedings below.
What Happens After You File
The clerk’s office first checks whether the petition complies with the Rules of Appellate Procedure. If it clears that screening, the petition circulates to the justices for a vote. Three justices must vote in favor of hearing the case for certification to be granted. When fewer than six justices are available to consider the petition, the threshold drops to two.2Justia.

If certification is granted, the case moves into a full briefing schedule. Both sides file detailed written arguments, and the court may schedule oral argument. If certification is denied, the Appellate Court’s decision becomes final and the case is over, absent a federal constitutional question that might support a petition to the U.S. Supreme Court.
If you need to stop a lower court judgment from taking effect while the Supreme Court considers your case, request a stay. This matters most in cases involving injunctions, property transfers, or custody arrangements, where carrying out the lower court’s order could cause irreversible harm before the Supreme Court rules.
