However, the pandemic has not guaranteed that such clauses are justified. According to Blake, ‘Covid-19 might only justify non-performance of the contract to the extent that it has all the characteristics that the contracting parties have agreed to attribute to the event of force majeure, it being necessary, however, to prove that the pandemic is characterised by the peculiarities summarized in the formula “externality, unforeseeability and unavoidability.”’
‘The proof that Covid-19 is an event beyond the control of the person invoking it and unforeseeable by him at the time of the conclusion of the contract does not seem to face any particular obstacles,’ he adds.
On the other hand, says Blake, proving that the pandemic precluded the performance of the contract by explaining effects that could not reasonably have been avoided or overcome may not be as easy. This is because there needs to be proof of the connection between Covid-19 and the impossibility of performing the contract. Meanwhile, the pandemic may not be considered as an event capable of precluding performance because the parties may need to consider the specific circumstances related to Covid-19 and its effects, including the adoption by governments of measures to contain the virus’ spread. These measures may also have prevented the terms of the contract being carried out.
