What these documents are

  • Commission decisions: Rulings by the Occupational Safety and Health Review Commission itself, the highest level of agency review. These are citable as Commission precedent, though a decision may have been appealed to a U.S. Court of Appeals after issuance.
  • ALJ decisions: Rulings by OSHRC Administrative Law Judges after a hearing. When no Commissioner directs review, an ALJ decision becomes a final order under 29 U.S.C. § 661(j): it binds the parties in that case but is not binding precedent in other cases.
  • Why finality matters: Every page here says which kind of decision you are reading, so you know whether it is precedent you can cite or a final order that only shows how one judge ruled on one set of facts.
  • Where they come from: Every page links the official OSHRC public release, and the full text on the page is that release. The plain-English summaries are written by Ezel.
