I do not think this is true. Do you have any proof? I‘m aware only of German court refusing to apply urgent procedure to unblock his bank accounts. The sanctions were applied not that long ago for him to get decision by German courts or ECJ.
No, this is a valid point. Court cases are usually playing out slowly amd carefully. So, in order to prevent harm to the parties involved caused by that slowness, injunctions can be issued by the court that can provide reasonable relief from immediate damages from the dispute that can't be compensated for or reversed later. In Germany, getting relief through an injunction really is about proving that lasting damage is caused while the case drags on. The full merrits of the case are explicitly excluded from consideration.
