All EU legislation (Treaties, Directives, Regulations etc.) and case law (decisions of the Court of Justice, and the GC & CST) are up on a website called EUR-LEX, usually in both HTML and PDF, and in every official language of the EU (at the time that the legislation or decision was made—earlier documents aren't retroactively translated into languages of countries that have joined subsequently).

Example of a CJEU decision: https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:61...

Example of legislative text (a Directive): https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32...

If you are comparing it with PACER, there are some differences - PACER contains loads more documents than you get on EUR-LEX including lots of procedural stuff, filings, and so on, while EUR-LEX only tends to have the court opinion, the Advocate-General opinion, and maybe a bit of procedural stuff, but not much else.

This is because the CJEU is in practice a court that only deals with matters of law that have been referred from a national court (or from another EU institution, like the Commission). Comparing the CJEU and a US federal district court is comparing apples with oranges.

If you compare to the US Supreme Court, note that all of the filings at that level are available for free. See, e.g., https://www.supremecourt.gov/docket/docketfiles/html/public/....

The EU just released the Justice scoreboard 2020 detailing the differences between all EU countries.

Court decisions are anonymized when published online in the EU. Is this the same in the US?
