What Is a Claim of Judicial Bias?
A judicial-bias claim alleges that a judge was not sufficiently impartial. Due process requires a fair tribunal, but the legal standard is demanding. Adverse rulings, criticism, or ordinary courtroom friction usually do not establish unconstitutional bias by themselves.

Important terms
Actual bias means a judge has a genuine disqualifying prejudice or interest.
Recusal is the process by which a judge steps aside under constitutional, statutory, or ethical rules.
The extrajudicial-source concept distinguishes opinions formed outside judicial proceedings from views based on material learned during the case, though the analysis is not absolute.
Why it can matter
Potential grounds can include a direct financial interest, significant personal involvement, or circumstances creating an objectively intolerable risk of bias.
The record should identify the specific facts, when they became known, any request for recusal, and the judge's response.
Limits to keep in mind
The Constitution sets a floor; statutes and state rules may impose additional recusal standards.
Claims can be forfeited or defaulted if not timely raised, and federal habeas review adds its own procedural and deferential limits.
