Procedural Posture

This Memorandum Opinion, issued by the United States District Court for the District of Columbia, addresses a motion to dismiss filed by the Defendant, the Republic of Sierra Leone, against the Plaintiff, Jenner & Block LLP. The Plaintiff initiated the action to recover alleged unpaid legal fees arising from its prior representation of the Defendant in various international arbitration and enforcement proceedings. The Defendant moved to dismiss the complaint pursuant to Federal Rules of Civil Procedure 12(b)(1) for lack of subject-matter jurisdiction, asserting foreign sovereign immunity, and 12(b)(6) for failure to state a claim.

Jurisdiction and FSIA Waiver

The principal jurisdictional issue before the Court was whether Sierra Leone was immune from suit under the Foreign Sovereign Immunities Act (FSIA). The Court determined that the implied waiver exception under 28 U.S.C. § 1605(a)(1) applied. By executing an engagement letter that contained a choice-of-law clause designating the laws of the District of Columbia and an exclusive forum selection clause in favor of D.C. courts, Sierra Leone implicitly waived its sovereign immunity. The Court further held that this waiver broadly encompassed all claims "concerning the engagement," thereby conferring subject-matter jurisdiction over both the express breach of contract claims and the alternative quasi-contractual claims.

Merits and Alternative Claims

In assessing the Rule 12(b)(6) motion, the Court found that the Plaintiff adequately pleaded claims for breach of both a written flat-fee agreement and a subsequent oral agreement for out-of-scope work. The Court rejected the Defendant's argument that prior payments extinguished the contractual obligations, noting that such factual disputes are inappropriate for resolution at the motion-to-dismiss stage. Furthermore, the Court permitted the Plaintiff's alternative claims for quantum meruit, unjust enrichment, and promissory estoppel to proceed. Although the existence of a valid express contract typically precludes quasi-contractual recovery, the Court applied the recognized exception allowing alternative pleading where the validity or scope of the underlying contracts remains contested by the Defendant.

Decision

The Court denied Sierra Leone's motion to dismiss in its entirety, allowing the Plaintiff's breach of contract and implied contract claims to advance to the next phase of litigation.
