Under Rule 15(c), when can an amendment that adds a new party relate back to the date of the original complaint?

• A. Only if the new party is the same as an original party.
• B. The amendment asserts a claim arising out of the conduct set forth in the original complaint and the new party received notice within the period for service.
• C. The amendment must be filed before the statute of limitations expires.
• D. The new party's identity must be corrected by substitution.

Answer: (B)

Relation back under Rule 15(c) happens when you’re adding a new party but keeping the same underlying facts. The essential idea is that the claim must arise out of the same conduct, transaction, or occurrence described in the original complaint, and the party you’re adding must have been given notice of the action within the time allowed for service. When those conditions are met, the amendment is treated as if it were filed on the date of the original pleading for purposes of the statute of limitations, which helps prevent prejudice to the newly named party and avoids unfair surprise. In this item, the amendment fits because it rests on the same conduct as the original dispute, and the new party received notice within the service period, satisfying the key criteria for relation back. The other concepts—such as substituting a party identity or requiring a separate filing before SOL—don’t capture the specific mechanism by which the claim is allowed to relate back to the original filing date under Rule 15(c).
