Under Rule 15(d), a plaintiff may supplement the complaint with a claim arising after the original filing if it relates to the underlying claim.

• A. No
• B. Yes, only with court approval
• C. Yes, only if the new claim is independent
• D. Yes, if it relates to the underlying claim and arises after filing

Answer: (D)

Rule 15(d) lets a plaintiff add a claim that arises after the original pleading if it relates to the underlying claim. The key is connection to the same transaction, occurrence, or subject matter already in dispute. The new claim isn’t required to be independent; it must simply grow out of the facts and issues in the original case. This keeps the lawsuit focused on related matters without starting a completely separate dispute. The other options miss this connection: one denies post-filing supplements outright, another adds an unnecessary condition about court approval, and another makes independence the trigger, which isn’t required.
