This site, COA.TX, has an incredibly straightforward tagline:
Quick Reference for Causes of Action and Affirmative Defenses in Texas. — Caselaw Snippets from Recent Texas Appellate Opinions.
Lawyers with a national practice (often driven by national clients) can spend a surprising amount of time pulling specific quotes from the relevant jurisdiction to either get complaints or answers filed or serve as the initial structure for various motions. The exact language of a cause of action may vary just slightly from state to state, and it never hurts to have the elements exactly right, since words, and the particularities of construction and meaning, are the tools of a good lawyer.
This is a great idea worth copying and extending to other jurisdictions, and even, if another tech-savvy lawyer were inclined, to collate into a wiki-style site to collect these statements.
Laws (and court opinions) belong to the people.
