Full Text of § 659a
Plain-English Summary
Once the notice of intention is on file, § 659a sets a tight, sequential schedule for the paperwork behind it. The moving party has 10 days to serve and file any brief and supporting documents, including affidavits. The other parties then get 10 days after that service to serve and file opposing briefs and counter-affidavits. The moving party gets a final 5 days to file a reply.
None of that is fixed forever. Any judge can extend these deadlines, for good cause shown by affidavit or by written stipulation of the parties, but only by up to 10 additional days.
