Courthouse Ethics and Transparency Act This bill requires federal judicial officers, bankruptcy judges, and magistrate judges to file periodic transaction reports disclosing certain securities transactions. The bill also requires online publication of judicial financial disclosure reports. Specifically, the bill requires federal judicial officers, bankruptcy judges, and magistrate judges to file reports within 45 days after a purchase, sale, or exchange that exceeds $1,000 in stocks, bonds, commodities futures, and other forms of securities. Additionally, the bill directs the Administrative Office of the U.S. Courts to establish a searchable internet database of judicial financial disclosure reports. The office must, within 90 days of the date by which a report must be filed, make the report available on the database in a searchable, sortable, and downloadable format. The bill does not require the immediate and unconditional availability of reports filed by a judicial officer or employee if the Judicial Conference finds that revealing personal and sensitive formation could endanger that individual or a family member of that individual.
