Unreported / Non-Citable
Background
Steven G. Cipres filed a slip-and-fall personal injury lawsuit against The Home Depot and related entities in California state court on September 16, 2024. He alleged that on September 14, 2022, he slipped and fell on an unmarked liquid in the plants and gardening section of a Home Depot store in El Cajon, California, asserting claims for negligence, willful failure to warn, and dangerous condition of public property. Home Depot removed the case to the U.S. District Court for the Southern District of California on September 25, 2025, based on diversity jurisdiction.
On February 2, 2026, Magistrate Judge Goddard issued a Rule 16 scheduling order requiring that any motion to join other parties or amend the pleadings be filed by April 6, 2026. On January 23, 2026, Home Depot served discovery responses identifying employee Steven Pruitt as the person allegedly responsible for watering plants and leaving water in the customer walkway. Despite learning this more than two months before the deadline, Cipres did not move for leave to amend and remand until May 22, 2026—over a month and a half after the deadline passed.
Cipres sought to add Pruitt as a defendant. Because Pruitt's joinder would destroy complete diversity, Cipres also moved to remand the case to state court under 28 U.S.C. § 1447(e). Home Depot opposed the motion, arguing it was untimely and that the factors governing post-removal amendments weighed against allowing the joinder.
The Court’s Holding
Judge Ruth Bermudez Montenegro denied the motion on two independent grounds. First, the court found it untimely under Rule 16(b). Cipres learned of Pruitt's identity on January 23, 2026, giving him over two months to move before the April 6, 2026 deadline, yet he filed on May 22, 2026—nearly four months after learning the information. The court found the delay unexplained and inexcusable: counsel's email exchanges showed awareness of the deadline, and Cipres offered no reason for waiting. Because the length-of-delay and reason-for-delay factors weighed heavily against him, he failed to show good cause or excusable neglect.
Second, even if the motion had been timely, the court held that the six factors under 28 U.S.C. § 1447(e) weighed against amendment: whether the new party is necessary under Rule 19, whether the statute of limitations would bar a state action, whether there was unexplained delay, whether joinder was sought solely to defeat federal jurisdiction, whether the claims against the new defendant appear valid, and whether denial would prejudice the plaintiff. Four factors favored Home Depot, one was neutral, and only the statute-of-limitations factor favored Cipres.
The court concluded that Pruitt was not a necessary party because California law does not require a plaintiff to join an employee when the employer is liable under respondeat superior, and any liability for Pruitt's acts would be imputed to Home Depot. Denial also caused no prejudice: Cipres could recover completely from Home Depot, and Pruitt's deposition was already scheduled. The court therefore denied both the motion to amend and the motion to remand.
Key Takeaways
- A party seeking to amend after a Rule 16 scheduling-order deadline must show both good cause and excusable neglect, and the court's primary consideration is the movant's diligence.
- Under 28 U.S.C. § 1447(e), a court may deny joinder of a diversity-destroying defendant added after removal and must scrutinize the amendment under a multi-factor test rather than Rule 15's permissive standard.
- California law does not require joining an employee as a defendant when the employer is liable under respondeat superior for the employee's acts within the scope of employment.
- An unexplained delay of nearly four months between learning new facts in discovery and moving to amend weighs heavily against excusable neglect, especially where counsel knew the deadline.
- Denial of leave to add an employee defendant does not prejudice the plaintiff when full recovery is available from the employer and discovery about the employee remains available.
Why It Matters
The decision reinforces the importance of complying with Rule 16 scheduling-order deadlines and the high bar for excusable neglect. The court's emphasis on Cipres's lack of diligence—despite having over two months to file before the deadline—warns that courts will not excuse unexplained delays when the movant had ample time to comply.
The ruling also clarifies 28 U.S.C. § 1447(e) in premises-liability cases: adding an employee who acted within the scope of employment is not necessary for just adjudication and will not force remand, because the employer bears responsibility under respondeat superior. This limits plaintiffs' ability to destroy diversity jurisdiction through strategic amendments designed solely to return a removed case to state court.
