Under FRCP 15(d), when may a party supplement a pleading with events that occurred after the original filing?

• A. Only with leave of court
• B. If the new claim relates to the underlying dispute and arises after the original filing
• C. If the new claim arises from a different transaction
• D. If the underlying dispute requires separate pleading

Answer: (B)

Rule 15(d) allows a party to file a supplemental pleading for events or transactions that occur after the date of the original pleading, but only if those post-filed matters relate to the underlying dispute and arise after the original filing. The court may permit such a supplement on motion with reasonable notice. This mechanism helps keep related developments in one action without forcing a new suit, as long as the new matter is tied to the same dispute. So the correct stance is that a post-pleading claim can be added when it relates to the underlying dispute and arises after the original filing. If the new matter is from a completely different transaction or controversy, or if it raises an unrelated issue that would require separate pleading, Rule 15(d) does not authorize the supplement.
