A couple of months ago Politico also reported that the EU had waived its right to sue in the AZ contract[1], so what gives? Would it kill Politico to give some additional context when a story seems to blatantly contradict its own reporting?
Why didn't you read the article I linked? It says:
"The contract makes clear the Commission and EU countries can't sue the drugmaker for a host of issues, most notably if there are 'delays in delivery of the Vaccine under this Agreement.'"
This seems to be a contractual dispute.
