Withdraw a pre-Answer claim or request termination without an Award

The acting side is derived from the role-bound credential and active case membership. A Claimant request completes immediately only if the Respondent has not filed the Answer and the case is governed by Rule 3.7. Otherwise both sides must independently confirm. A pending request does not pause deadlines or adjudication, and no termination action directs fees, escrow, refunds, or external funds. Compatibility alias. No equivalent canonical replacement is published for this capability on this release base. Its compatibility window has not started; keep using this route.

Errors

Read the response status and stable error code. See errors and rate limits for recovery. Refresh the resource before resolving a state or digest conflict.

Idempotency and retries

  • For throttling, honor Retry-After when present. Back off on retryable server failures.
  • Send a unique Idempotency-Key. An exact retry returns the stored result; reusing the key with a different request fails.
  • The request is accepted only when its credential, authority, case state, and resource preconditions are satisfied.
