Kolosai v. Azem

**What happened:** Employee Kolosai challenged the validity of an arbitration agreement with employer Azem, claiming the signature on the document was not genuine. Arbitration agreements require workers to resolve disputes through private arbitration rather than going to court. The case involved questions about whether an expert witness was qualified to testify about the signature and whether the trial court had properly determined the signature was valid. **What the court decided:** The appellate court sent the case back to the lower court for further proceedings (remanded). The court found that the trial court had not clearly abused its discretion in allowing the expert witness to testify about the signature's validity. The court also determined that the lower court's finding that the signature was genuine was supported by the evidence. **Why this matters for workers:** This case highlights how difficult it can be for employees to challenge arbitration agreements, even when questioning whether they actually signed them. Workers should carefully review any arbitration clauses in employment contracts, as these agreements limit their ability to sue employers in regular courts. The ruling shows courts give significant deference to trial court decisions about signature validity and expert witness qualifications in these disputes.
