Whether Baxter waived appellate review by failing to object to the magistrate judge's report and recommendation.
Holding
No. Baxter waived challenges to factual findings but retained her right to challenge the legal conclusion that substantial evidence supported the Secretary's denial of benefits.
Reasoning
The Federal Magistrates Act requires de novo district-court review of portions of a magistrate's report to which objections are made, but it does not itself mandate a complete appellate-waiver rule for parties who fail to object. Although some circuits impose such a rule, the Ninth Circuit had adopted a narrower approach.
Under Ninth Circuit precedent, failure to object waives a challenge to the magistrate's factual findings, but not a challenge to the magistrate's legal conclusions. Whether an ALJ's decision is supported by substantial evidence is a question of law. Baxter therefore could appeal the conclusion that the record substantially supported the Secretary's finding of no disability.
