On Thursday, Poland's Constitutional Tribunal ruled that key articles of one of the EU's primary treaties were incompatible with Polish law, in effect rejecting the principle that EU law has primacy over national legislation in certain judicial areas.
The EU has condemned some of the sweeping changes made to the Polish judiciary.
Both (Poland's prime minister Mateusz) Morawiecki and Poland's most powerful politician, PiS chairman Jaroslaw Kaczynski, insist Poland wants to stay in the EU.
They accuse the country's fragmented opposition of spreading "fake news" to frighten an electorate that overwhelmingly supports membership, even if more Poles now voice concerns about losing sovereignty to the EU.
They acknowledge membership has given Poland access to billions of euros to invest in projects that have visibly transformed the country's landscape, as well as access to the single market.
Poland has much to lose if it does decide to leave the EU though perhaps countries like France and Germany are being too quick to jump.
