Is COVID-19 an Act of God and/or Will COVID-19 Be a Defense Against Failure to Perform?

Is COVID-19 an Act of God and/or Will COVID-19 Be a Defense Against Failure to Perform?

This is the second in a series of alerts on Force Majeure and Common Law Defenses against failure to perform contracts. In our first alert, we discussed the elements of a force majeure clause and looked at how various states have interpreted force majeure clauses. We focused on how most states take a narrow view of these provisions and they adhere to the plain meaning of the force majeure provisions. This alert takes a look at one event often listed in force majeure clauses – Acts of God.

As discussed in our previous alert, some courts will excuse performance of a contract only if the event causing the breach is actually listed in the force majeure clause. Among the list of events that would most likely excuse a failure to perform under a contract due to COVID-19 would be if the force majeure provision listed pandemics, epidemic, health emergencies or government orders or regulations. While your contract may not list these events, most force majeure provisions do include an Act of God.

In this alert we look at whether it is likely that courts will find that COVID-19 is an Act of God and if such consideration will actually be a defense against performance of a contract.

In general, courts have found that an Act of God is a natural event that would not occur by the intervention of man, but proceeds from physical causes. As noted in the chart below, some states further require that the event is not reasonably preventable by human foresight, strength or care.

Is COVID-19 a natural event? According to various new sources, U.S. intelligence and national security officials are investigating the possibility that the virus originated in a lab. If the virus originated in a lab, then COVID-19 would not qualify as having arisen from a natural event. The Centers for Disease Control indicates that it came from an animal source. Does that qualify as a natural event? U.S. case law does not provide sufficient guidance on this point. When describing Acts of God, U.S. case law references hurricanes and tornadoes and similar events, but does not generally reference disease. Whether a virus from an animal source is caused by nature will ultimately be left to the courts to decide.

Assuming that the virus satisfies the definition of an Act of God it still may not excuse performance. Courts generally require that the Act of God be the sole event that causes the breach and have decided that if there is an intervening factor between the Act of God and the breach, that the Act of God will not excuse performance.

This is where the challenge is greatest for companies. For most companies, it is not the virus that is preventing performance breaches typically resulting from government orders that shut down non-essential businesses, gaps in supply chain or mandatory work- from-home orders. As a result, litigants will face the uphill battle of connecting COVID-19 as the direct and sole event that caused the breach of performance. This will likely be a high burden. Aside from beef or poultry factories that have become overrun by the virus, it is difficult to see a breach as the direct result of COVID-19, that qualifies as an Act of God and excuses performance. The novelty and breadth of the impact of COVID-19, however, is likely to result in a checkerboard of results which will be tailored to specific situations and circumstances.
