The short answer is yes. The longer answer is that courts can only make decisions on the evidence presented to them. Since only one side is represented (the whole point being not to tip off the person being snooped on) they don't get balanced evidence.
English courts are the same, magistrates and judges effectively rubber stamp TV licensing, utility forced access, search warrants etc.
Courts can, and do, pick holes in the argument but if the police have put a consistent case together then there is little the court can do.
Not ideal but that's life. Awaiting lots of downvotes from people who live in a fantasy world.
