Court Ruling — C.D. Cal, 2025 #10706765

**What Happened** Workers sued 3M Company claiming the company failed to properly warn them about dangers associated with 3M products. During the lawsuit, both sides disagreed about what information could be gathered through depositions (recorded questioning of witnesses under oath). 3M tried to block some depositions, while the workers wanted to force 3M to provide more information. **What the Court Decided** The court made a split decision. It allowed the workers to gather information about how 3M designed its products, since this information was relevant to proving whether 3M failed to give proper warnings. However, the court ruled that the workers' lawyers had to follow proper legal procedures when requesting depositions from individual witnesses - they couldn't just serve subpoenas on 3M itself but had to properly serve each individual witness directly. **Why This Matters for Workers** This ruling shows that workers can still pursue important evidence about product design when claiming their employer failed to warn them about workplace dangers. However, it also demonstrates that workers and their lawyers must carefully follow all procedural rules when gathering evidence, or risk having their requests denied by the court.
