The EJC is there to handle discrepancies between EU regulations and nations (not fully/correctly) implementing them.
So this is not a general supreme court. Cases which don't run in local law conflicting EU regulations can't end up there.
EU regulations don't cover everything and do often have large margins of interpretation. They are generally not laws but regulations about making laws.
So there is a good chance your case will never have a chance to end up there even if it continues to escalate.
Edit: also the ECJ does work different in the results they produce then you think, e.g. they can rule that a certain court action/law/etc. is in beach if regulations and anull it to some degree, but that didn't mean they can e.g. force gurillamail to be rehosted. At most they could "annul" a france court discussion that the takedown for given reasons was legal. Which seems similar but is a massive difference as they then could argue that the takedown was still legal due to other reasons and still win (or just delay it further).
