Timely Motion After Fact Discovery
Sterling Manufacturing sued Sierra Solutions for breach of a supply contract. After fact discovery closed on March 1, Sterling moved for summary determination on March 20, attaching production logs and expert declarations showing no contamination. Sierra opposed with conflicting test results. The court granted the motion because no genuine factual dispute remained on causation.
Motion Filed Within Default Window
Summit Bank sued Synergy Systems for loan default. Fact discovery closed March 1 and expert discovery remained open until April 15. Summit filed its motion on March 20 relying solely on fact-discovery materials. The court treated the motion as timely and proceeded to the merits because the scheduling order did not extend the thirty-day period.

Common questions
Frequently Asked
3
When may a party file a motion for summary determination under the default federal timing rule?+
A party may file the motion at any time until thirty days after the close of all discovery unless a local rule or court order sets a different deadline. The rule measures the period from the close of all discovery, though a scheduling order that separates fact and expert phases may effectively trigger the period after fact discovery alone.
Supporting sources
What must a court do when matters outside the pleadings are presented on a Rule 12(b)(6) motion?+
The court must convert the motion to one for summary determination under Rule 56 if it does not exclude the outside materials. All parties must then receive a reasonable opportunity to present pertinent material before the court rules.
Supporting sources
Does a court need to state findings of fact when it rules on a motion for summary determination?+
No. Rule 52(a)(3) expressly exempts summary judgment rulings from the requirement that a court state findings of fact and conclusions of law after a nonjury trial.
