The Court of Justice delivered today its judgment in case C‑287/17 (Česká pojišťovna a.s. v WCZ, spol. s r.o.), which is about Directive 2011/7/EU of the European Parliament and of the Council of 16 February 2011 on combating late payment in commercial transactions:

“Article 6 of Directive 2011/7/EU […] must be interpreted as recognising that a creditor claiming compensation for the costs associated with sending reminders to a debtor due to the latter’s late payment is entitled to obtain reasonable compensation, on that basis and in addition to the fixed amount of EUR 40 laid down in Article 6(1) of that directive, for the purposes of Article 6(3) thereof, in respect of the part of those costs which exceeds that fixed amount”.
