It is a fundamental principle in civil litigation that there shall be full disclosure of all matter that is material and necessary in the prosecution or defense of an action. However, a party is not entitled to unlimited, uncontrolled, and unfettered disclosure, and the supervision of discovery is left to the trial court's broad discretion. Absent an improvident exercise of that discretion, its determination will not be disturbed on appeal Pursuant to CPLR 3103(a), the Supreme Court may issue a protective order precluding disclosure that is palpably improper in that it seeks irrelevant and/or confidential information, or is overly broad and burdensome.
