The Late Amendment and the Borrowed Expert Report
Plaintiff filed suit in federal court on January 10, alleging breach of a construction contract. The scheduling order set a deadline of May 1 for amendments to pleadings and a deadline of June 15 for expert disclosures. On June 20, plaintiff moved to amend the complaint to add a fraud count, attaching an expert report it had received from a consultant on June 10 but never disclosed. Defendant opposes, arguing undue delay and prejudice; trial is set for November 1. Plaintiff responds that the fraud theory only became viable after documents were produced in May, and that the expert is a rebuttal expert who need not be disclosed under the scheduling order. The proposed amendment would add $400,000 in punitive damages and a new party. The court has not yet held a pretrial conference.

Standard. After a scheduling order's amendment deadline passes, Rule 16(b)(4) requires a showing of good cause before Rule 15(a)(2)'s liberal amendment standard even applies. The court considers the diligence of the movant, the reasons for delay, and prejudice to the opponent.
Application.
- Diligence: Plaintiff waited roughly six weeks after the May document production to move. That is not per se dilatory, but plaintiff must explain the gap. The June 10 consultant report is not a justification for delay in pleading; the fraud theory's viability depends on the underlying documents, not the expert's opinion.
- Reason for delay: If the May production genuinely first revealed the fraud, good cause exists for the timing of the motion. The court should require a specific proffer of which documents and when.
- Prejudice: Trial is over four months away. Adding a new party and $400,000 in punitive damages increases discovery scope, but the defendant can seek a continuance or bifurcation. Prejudice must be more than the cost of defending new claims.
Conclusion. Likely grant as to the fraud count if plaintiff shows the May production was the first indication; deny or condition as to the new party absent a showing of that party's role. The expert issue is separate and should be addressed under Rule 26.
2. Is the consultant a rebuttal expert exempt from the June 15 disclosure deadline?

No, on these facts. Rule 26(a)(2)(D) sets default deadlines for disclosures, and a party may not use a rebuttal designation to smuggle in case-in-chief opinion. The label controls substance, not form.
- If the report affirmatively supports the fraud count (i.e., plaintiff's own burden), it is a case-in-chief expert requiring a full Rule 26(a)(2)(B) report by June 15. The scheduling order's deadline governs.
- A true rebuttal expert responds to an opponent's disclosed expert and may be disclosed within 30 days of the opposing disclosure under the default rule, but the scheduling order here may displace that default.
Consequence. Failure to disclose triggers Rule 37(c)(1): exclusion unless the failure was substantially justified or harmless. Given trial is months away, the court could allow a late disclosure with costs and a deposition, but plaintiff should not assume automatic admission. The safer ruling: treat the report as case-in-chief, find the late disclosure not substantially justified absent explanation, and order the expert's deposition at plaintiff's expense as the harmless-error remedy.
