Rule of Law:
An 'unless' oil and gas lease terminates automatically if the lessee fails to pay the correct amount of delay rentals. An equitable defense of mutual mistake is unavailable to a lessee who acts negligently and fails to cure the underpayment after receiving notice of the error from the lessor.
Facts:
- On July 25, 1972, Matt and Ruth Schwartzenberger leased their property to the William Herbert Hunt Trust Estate for oil and gas exploration.
- The lease was an 'unless' type, requiring an annual delay rental payment of $1.00 per acre if drilling operations were not commenced by the anniversary date.
- Due to a mutual mistake, both parties believed the Schwartzenbergers owned 398.31 mineral acres, when they actually owned 406.24 acres.
- Relying on the incorrect acreage count, the Trust Estate underpaid the delay rentals due in July 1973 and July 1974.
- In early 1974, the Schwartzenbergers notified the Trust Estate of the underpayment and requested that the lease be canceled.
- On March 25, 1974, the Schwartzenbergers sent a formal notice of termination to the Trust Estate.
- On April 1, 1974, the Trust Estate responded by denying any error, insisting their payment was correct, and refusing to release the lease.
- The Schwartzenbergers' attorney sent another letter on April 8, 1974, giving the Trust Estate a deadline to respond before a lawsuit would be filed, but the Trust Estate still did not tender the difference.
Procedural Posture:
- Matt and Ruth Schwartzenberger initiated an action against the William Herbert Hunt Trust Estate in a state trial court to terminate an oil and gas lease.
- The trial court found that a mutual mistake had occurred regarding the mineral acreage.
- The trial court entered a judgment in favor of the Hunt Trust Estate, reforming the lease to reflect the correct acreage and ordering the Trust Estate to pay the deficient bonus and rental amounts.
- The Schwartzenbergers, as appellants, appealed the trial court's judgment to the Supreme Court of North Dakota.

Issue:
Does an 'unless' oil and gas lease automatically terminate when the lessee, due to a mutual mistake of fact regarding mineral acreage, fails to pay the full amount of delay rentals and does not cure the deficiency after being notified by the lessor?
Opinions:
Majority - Erickstad, Chief Justice
Yes, the 'unless' oil and gas lease automatically terminates under these circumstances. An 'unless' lease terminates ipso facto (automatically) upon the failure to drill or pay the correct delay rental amount. The court distinguished this case from precedents like Humble Oil v. Harrison, which provide equitable relief for good faith mistakes, because here the Trust Estate was negligent in its title search and, more importantly, failed to cure the underpayment after receiving multiple notices from the Schwartzenbergers. Instead of attempting to correct the error, the Trust Estate denied its obligation, thereby forfeiting any claim to equitable relief and allowing the lease to terminate by its own terms.
Analysis:
This decision reinforces the strict, common-law rule in North Dakota that 'unless' leases terminate automatically upon failure to strictly comply with their terms, particularly the payment of delay rentals. The court signals that while it might consider equitable exceptions for a good-faith mutual mistake in the future, such an exception will not protect a lessee who is negligent or fails to act reasonably to cure a defect upon receiving notice. This holding places a significant burden on lessees to ensure the accuracy of their payments and to respond promptly and constructively to landowners' claims of error, rather than denying them outright.
