Amazon France will take its case over worker health and safety related to COVID-19 to France’s highest court.

The company announced late Thursday that it would ask the Court of Cassation to rule on an appeals court order that Amazon should deliver only essential items until it had completed an assessment of the risks linked to the novel coronavirus in consultation with workers’ unions, or face heavy fines.

“The reasons for this choice will be directly presented by the company to the courts and to the parties concerned,” Amazon France said in a statement.
