I mean, yes, that is what happens to Member States who don't bring in legislation relating to the EU competencies when passed. That's... y'know, the point.
Under Article 258 of the Treaty on the Functioning of the EU (TFEU), if the Member State concerned does not comply with the reasoned opinion within the period laid down by the Commission, the latter may bring the matter before the Court of Justice of the European Union. Additionally, under Article 260(3) TFEU, the Commission can call on the Court of Justice of the EU to impose financial sanctions on the Member States that failed to fulfil their obligation to notify measures transposing a legislative directive
Pretty much this. And it's not the first time this happens.
And it's usually not an issue of "we don't want to" (I don't remember if any country overwhelmingly voted against it) but more of legislative delays (kicking the can) and such.
