Not sure exactly what evidence the defense would be required to share..the prosecution is obligated to share any exculpitory evidence they might have, along with evidence they intend to introduce at trial,and a list of witnesses to be called..the defense normally dosent have a obligation to disclose much that they might have (theres a few laws PROHIBITTING it in fact, along with a constitutional right against self incrimination) so unless the defense knowingly suborned purgery ,Thier probably safe. If they knowingly allowed a false evidence or testimony,then you might have something to move on to the court or ethics committee..Part of the defenses job is basicly ,concealing evidence,thats one of the problems with our legal system.Can you sue the defendants lawyers in federal court for concealing evidence in a state case?
You first of all have to prove that it exists.





How would you do this?





Then you have to prove that the lawyers have seen it.

It is difficult to sue lawyers..
There is no rule regarding mandatory disclosure of evidence in all courts. Federal courts have more broad disclosure rules than state courts, but if your lawyer doesn't ask the right questions during discovery, you might get blindsided at trial. It might be your attorney's fault. Also, in some states (California) there's a litigation privilege which prevents subsequent suits based on conduct during a prior trial.

Unless the defendant is the Government, I don't believe they have to disclose anything to you. Discovery is part of your atty's job in the course of the suit. They are under no obligation to hand you information that will hurt their case unless under supoena
Your assumption that there is some general rule that requires voluntary disclosure of everything known to each of the parties is incorrect. There are many rules of discovery but none so broad as you suggest. Suing someone in federal court generally requires a federal cause of action. No federal law governs the disclosure of evidence in a state civil action.
federal laws do not state that evidence can be opened. They do allow some to be conceealed, but it is at the judges discernment if concealed evidence can be requested or not. Filing suit against the defences attorney will not hold.
You have to prove the evidence exists. If the Judge has already made a ruling, then the case is put to rest. Good Luck.
