Are federal equitable reimbursement claims subject to Utah's statute of limitations? CIG Exploration v. State of Utah Explained

Background and Facts

In the early 1980s, CIG Exploration, Inc. paid royalties to Utah based on federal Natural Gas Policy Act “tight sands” pricing for gas produced from state leases. After the Federal Energy Regulatory Commission ruled in 1988 that such pricing violated a 1973 settlement agreement, CIGE filed suit in 1991 seeking reimbursement of allegedly overpaid royalties under two theories: federal common law equitable reimbursement and breach of implied covenant of good faith and fair dealing.

Key Legal Issues

The central issue was whether Utah’s four-year statute of limitations under section 78-12-25(1) applied to both claims, or whether federal equitable principles like laches governed the federal common law claim and the six-year statute under section 78-12-23(2) applied to the contractual covenant claim.

Court’s Analysis and Holding

The Utah Supreme Court affirmed summary judgment for the state, holding that both claims were time-barred under the four-year statute. For the federal equitable claim, the court applied the general rule that federal courts apply analogous state statutes of limitations, rejecting CIGE’s argument that equitable laches should apply instead. The court noted that even under laches, CIGE’s delay was unreasonable given notice of potential claims as early as 1982.

For the implied covenant claim, the court held that reimbursement claims are not founded on contractual rights unless expressly written in the contract. Instead, such claims sound in implied assumpsit for monies had and received, triggering the four-year limitation period. The court emphasized that CIGE had adequate time to file suit after FERC’s 1988 ruling but before the limitations period expired in April 1989.

Practice Implications

This decision establishes that reimbursement claims seeking recovery of overpayments are generally subject to Utah’s four-year statute of limitations regardless of whether framed as federal equitable claims or contractual breaches. Practitioners should file such claims promptly upon discovering the basis for recovery, as equitable tolling doctrines provide limited protection against statutory deadlines absent extraordinary circumstances.
