Facts

In 1978, NIPSCO agreed to buy about 1.5 million tons of coal annually from Carbon County for 20 years under a fixed-quantity contract with a price floor and escalation provisions; by 1985 the price had risen to $44 per ton. In 1983 and 1984, the Indiana Public Service Commission ordered NIPSCO to make good-faith economy purchases of cheaper electricity from neighboring utilities when possible, rather than generate electricity internally at higher cost. Because electricity from other utilities became cheaper than generation using Carbon County coal, NIPSCO stopped accepting coal and claimed its contractual duties were excused by the Commission's orders, by force majeure, frustration, impracticability, and by alleged illegality under section 2(c) of the Mineral Lands Leasing Act due to Carbon County's connection to the Union Pacific corporate family. Carbon County's mine later shut down after the district court entered a damages judgment instead of ordering specific performance.

Issue

Whether NIPSCO was excused from its long-term coal purchase obligations because regulatory orders made performance uneconomical, because the contract was allegedly tainted by a possible violation of section 2(c) of the Mineral Lands Leasing Act, or because equitable relief and bond requirements should alter the judgment. Also at issue was whether the district court committed reversible error in expediting trial and refusing a continuance.

Rule

A force majeure clause does not excuse a party from the normal market risks allocated by a fixed-price, fixed-quantity contract unless the governmental action actually prevents performance or use in the contractual sense rather than merely making performance uneconomical. Related doctrines such as frustration and impracticability likewise do not relieve a party from a risk the contract expressly assigns to it. Illegality is not an automatic defense to enforcement of a lawful contract when the alleged statutory violation is collateral to the contract itself; courts must weigh the costs and benefits of nonenforcement. Specific performance is unavailable when damages are adequate and when compelling performance would force uneconomical production.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

Lakefront Power Cooperative in Milwaukee signed a 15-year contract to buy a fixed annual quantity of biomass pellets from Prairie Ridge Fuels at a price floor with escalation clauses. Two years later, Wisconsin utility regulators ordered Lakefront to purchase cheaper electricity on the spot market whenever available and refused to let Lakefront recover pellet-related losses from ratepayers if cheaper power could be bought elsewhere.

If Lakefront stops taking pellets and argues that the regulatory order triggered a force majeure clause excusing performance when governmental action partly prevents the buyer's use of the goods, what is the strongest response?

Explanation. A force majeure clause does not protect a party from the ordinary downside risk assigned by a fixed-price, fixed-quantity contract. Government action that merely makes performance unprofitable, or prevents the buyer from shifting losses to customers, does not 'prevent' use in the relevant sense. The majority reasoned that such regulation simulates market discipline rather than physically or legally blocking contractual performance.
