Researching a matter
- Describe the facts plainly, for example: "A Tulsa oilfield worker was burned in a flash fire at a well site operated by a contractor's customer."
- Search Oklahoma decisions first, then Tenth Circuit decisions if you're in federal court.
- Read the law at issue - here, 23 O.S. § 13 on comparative negligence, and the workers' compensation exclusivity provisions - and check treatment before relying on any case.
