Saul Goodman is the defendant, Matt Murdock is the prosecutor.
Saul is defending a guilty client.
They are involved in the full trial proceeding, including statements, discovery, ect all the way up to the final trial.
They can use dirty tricks, manipulation, or the Daredevil persona to gain advantages is the courtroom. The only rule is that it must be settled in court. Matt cannot use Daredevil directly on Saul, and Saul cant have Matt assassinated.
If they are given free reign to finagle the legal system, who would win the legal case?
