The Polish Air Navigation Services Agency (PANSA) said on Friday it had lodged the objection in a bid to have the freeze lifted and its finances unblocked.
It stressed the underlying case has nothing to do with its own operations – the funds were seized because Eurocontrol, the European air safety body, was carrying out enforcement of the court's decision.
PANSA said it was working closely with the Polish State Treasury and government legal representatives, alongside other stakeholders, to protect its position.
A preliminary hearing is due in mid-August.
The agency had earlier warned that route charges collected via Eurocontrol make up more than 80 percent of its revenue.
It insisted, however, that there was no risk to operations or jobs.
Prime Minister Donald Tusk said last Friday his government would not leave the agency without financial support, noting the dispute stems from a vaccine contract signed by the previous administration.
Infrastructure Minister Dariusz Klimczak told private broadcaster Polsat News that around PLN 1 billion (EUR 230 million) in extra funding may be needed to keep the agency running through the end of the year, though he added it currently has enough to operate normally in the coming months.
The legal dispute centres on a European Commission contract with Pfizer, signed on behalf of EU member states, for Covid-19 vaccine deliveries.
Poland refused to take delivery of part of its order in 2022, citing the changed epidemic situation and the war in Ukraine.
Pfizer took the matter to a Brussels court in September 2023.
On 1 April 2026, a Belgian court of first instance ruled Poland must accept around 64 million doses and pay the company PLN 5.644 billion (EUR 1.3 billion), plus roughly PLN 170 million (EUR 39 million) in legal costs.
Poland's health ministry has said it intends to use all available legal means to overturn the non-final ruling; it has 60 days from formal notification to lodge an appeal.
