Getting dragged to court is disruptive, unsettling and expensive.
Most of EU has judges that are interested in a just resolution, not just being "an independent arbiter" of two researchers.
This all sounds quite lucrative for the lawyers and notaries. It remains disruptive, unsettling and expensive, not to mention unnecessary, for everyone else. Depending on which of the EU’s 28 member states’ courts one finds oneself dragged into, what you’re proposing could be years of distraction.
Nobody will do this, no sane legal department signs this off or approves of such behavior. Doing otherwise is a great way to incinerate their legal licenses. There are fines for behavior like that.
The best outcome for the suing party of such a scenario is a 5 minute court room appearance in which the judge slaps you with a restraining order and closes the case.
This has literally never been an escalating problem in european courtrooms to my experience because judges don't like that behavior and laws exist to prevent it.
Dubious. The other lawyer will claim they believed you had read the complaint and therefore that they were acting in good faith, and will see no punishment at all.
Or I just ban Tor users from creating reports, I'm not forced to enable abuse, if they have an actual complaint they can use their real internet connection. End of story.
If you are on holiday at that time, the court will in almost all cases instruct the other party to wait until you return at which point you can respond to the C&D.
