Edward Douglass White, District of Columbia v. Bailey…
“ In determining whether an agreement to arbitrate involves the power to contract, we eliminate at once from consideration consents to arbitrate made under a rule of court, by consent, in a pending suit, and shall consider only whether an agreement to arbitrate not under rule of court or within the terms of a statute enacted for such purpose is or is not a contract. We do this because there is no pretense in the case at bar that the submission to arbitration was under a rule of court or equivalent thereto. ”
