California Case Law Search: Search California Case Law, Court Opinions, and Precedent
California produces more published opinions than any other state, which is exactly why finding the on-point one is hard. Ask your question in plain English and get California precedent back with the holding and a citation you can check in the official reporter.

In short
California case law search means finding published opinions of the California Supreme Court and the California Courts of Appeal that decide the issue in front of you. With Cases you describe the issue in plain English, such as whether an employer can enforce a non-compete against a departing employee in California, and you get on-point California precedents back as headnote cards, each with a plain-English summary, the holding, and a real citation you confirm in the official reporter. There is no boolean syntax to build and no sales call to sit through. Two California rules shape any search here. Under Auto Equity Sales v. Superior Court (1962) 57 Cal.2d 450, every published Court of Appeal decision binds every superior court in the state, not just the courts in that appellate district. And under California Rule of Court 8.1115, an unpublished California opinion generally may not be cited or relied on at all, so confirming that a case is published is part of the research, not an afterthought. Cases is informational research, not legal advice. You verify each citation before you rely on it.
Who binds whom
Which California court binds your case, and where the opinion is published
| Court | Precedential weight | Reporter |
|---|---|---|
| Supreme Court of California | Highest court. Binds every court in California. | Cal. 5th (official), P.3d, Cal. Rptr. 3d |
| California Courts of Appeal | Six appellate districts. A published decision binds all superior courts statewide. | Cal. App. 5th (official), P.3d, Cal. Rptr. 3d |
| Superior Courts | Trial courts, one per county. Decisions are not binding precedent. | Generally unreported |
| Ninth Circuit and U.S. district courts | Bind on federal questions. Persuasive only on questions of California law. | F.4th, F. Supp. 3d |

How to search
Three steps from a California legal question to an on-point case you can cite
01
Ask the question, not the keyword
Describe the California issue the way you would explain it to a colleague. No terms and connectors, no proximity operators, no guessing at the phrasing a headnote editor used.
02
Read the holding on the card
Each result comes back as a headnote card with a plain-English summary and the holding, so you can tell in seconds whether the case is on point before you open the full opinion.
03
Verify the citation at the source
Every card shows a real citation. Confirm it in the official reporter and check it is still good law. You stay the gatekeeper on anything that goes into a filing.
Where it earns its keep
California research areas where finding the on-point case is the whole job
Employment and wage-and-hour
California employment law is heavily litigated, from meal and rest breaks and PAGA claims to non-compete enforceability under Business and Professions Code section 16600.
Landlord-tenant and real property
Local rent control and state-level tenant protections generate a steady stream of appellate authority worth checking before you file.
Consumer and privacy
The CCPA and CPRA, the UCL, and the Song-Beverly Act keep producing new published opinions, which makes recency checks matter here more than in most states.
Free California case law sources, and where they run out
You can read California appellate opinions for nothing. The state courts publish them, Google Scholar indexes them, and CourtListener carries them with a usable search. If you already know the case you want, a free source will get you the text in under a minute, and there is no reason to pay for that.
Free sources run out in two places. The first is finding a case you do not already know about: keyword search over raw opinion text rewards whoever guesses the court's vocabulary, and a California opinion that decides your exact issue in different words stays invisible. The second is verification. None of the free options tells you whether a case has been overruled, distinguished into nothing, or superseded by statute, which is the check that keeps a brief out of trouble.
Cases sits in the first gap. You ask in plain English, you get on-point California precedent with the holding on the card, and you get a real citation to confirm at the source. It is priced on the page starting at 29 dollars per month, not quoted after a sales call like the incumbents, and you can read the honest comparison on our Westlaw alternative page. It is informational research, not legal advice, and you verify every citation before you rely on it.
Questions researchers ask
California case law research, answered
How do I search California case law?
To search California case law, start with the issue rather than the keyword: describe the legal question in plain English, then narrow to published opinions of the California Supreme Court and the Courts of Appeal. Free sources include the official California Courts opinions site, Google Scholar, and CourtListener. Paid platforms add editorial headnotes and citator checks. Confirm any case you find in the official reporter before you cite it.
Are California Court of Appeal decisions binding on all trial courts?
Yes. Under Auto Equity Sales v. Superior Court (1962) 57 Cal.2d 450, a published decision of any California Court of Appeal binds every superior court in the state, not only the superior courts inside that appellate district. When two districts conflict, a trial court may choose which to follow, so checking for a split across districts is part of thorough California research.
Can you cite unpublished California opinions?
Generally no. California Rule of Court 8.1115 says an opinion not certified for publication must not be cited or relied on by a court or a party, with narrow exceptions such as law of the case, res judicata, collateral estoppel, and discipline proceedings. This is stricter than federal practice, where Federal Rule of Appellate Procedure 32.1 permits citing unpublished federal opinions issued after 2007.
Where can I find California case law for free?
The California Courts website publishes the opinions of the Supreme Court and the Courts of Appeal, including a list of recent filings. Google Scholar and CourtListener both carry California appellate opinions and are free to search. Free sources are good for retrieving a case you already know about, but they do not tell you whether it is still good law, so verify with a citator before relying on it.
What reporter is California case law published in?
California Supreme Court opinions appear in the official California Reports, now California Reports Fifth Series (Cal. 5th), and Court of Appeal opinions in California Appellate Reports Fifth Series (Cal. App. 5th). Both are also carried in the regional Pacific Reporter (P.3d) and in West's California Reporter (Cal. Rptr. 3d). California Style Manual and Bluebook forms differ, so match the form your court expects.
