    any person whose wire, oral, or electronic communication is
    intercepted, disclosed, or intentionally used in violation of this
    chapter may in a civil action recover from the person or entity,
    other than the United States, which engaged in that violation such
    relief as may be appropriate.
      (b) Relief. - In an action under this section, appropriate relief
    includes - 
        (1) such preliminary and other equitable or declaratory relief
      as may be appropriate;
        (2) damages under subsection (c) and punitive damages in

        (3) a reasonable attorney's fee and other litigation costs
      reasonably incurred.

      (c) Computation of Damages. - (1) In an action under this
    section, if the conduct in violation of this chapter is the private
    viewing of a private satellite video communication that is not

    Commission that is not scrambled or encrypted and the conduct is
    not for a tortious or illegal purpose or for purposes of direct or
    indirect commercial advantage or private commercial gain, then the
    court shall assess damages as follows:
        (A) If the person who engaged in that conduct has not
      previously been enjoined under section 2511(5) and has not been
      found liable in a prior civil action under this section, the
      court shall assess the greater of the sum of actual damages
      suffered by the plaintiff, or statutory damages of not less than
      $50 and not more than $500.
        (B) If, on one prior occasion, the person who engaged in that
      conduct has been enjoined under section 2511(5) or has been found
      liable in a civil action under this section, the court shall
      assess the greater of the sum of actual damages suffered by the
      plaintiff, or statutory damages of not less than $100 and not
      more than $1000.

      (2) In any other action under this section, the court may assess
    as damages whichever is the greater of - 
        (A) the sum of the actual damages suffered by the plaintiff and
      any profits made by the violator as a result of the violation; or
        (B) statutory damages of whichever is the greater of $100 a day
      for each day of violation or $10,000.

        (1) a court warrant or order, a grand jury subpoena, a
      legislative authorization, or a statutory authorization;
        (2) a request of an investigative or law enforcement officer
      under section 2518(7) of this title; or
        (3) a good faith determination that section 2511(3) or
      2511(2)(i) of this title permitted the conduct complained of;

    is a complete defense against any civil or criminal action brought
    under this chapter or any other law.

    commenced later than two years after the date upon which the
    claimant first has a reasonable opportunity to discover the
    violation.
      (f) Administrative Discipline. - If a court or appropriate
    department or agency determines that the United States or any of
    its departments or agencies has violated any provision of this
    chapter, and the court or appropriate department or agency finds
    that the circumstances surrounding the violation raise serious
    questions about whether or not an officer or employee of the United
    States acted willfully or intentionally with respect to the
    violation, the department or agency shall, upon receipt of a true
    and correct copy of the decision and findings of the court or
    appropriate department or agency promptly initiate a proceeding to
    determine whether disciplinary action against the officer or
    employee is warranted. If the head of the department or agency
    involved determines that disciplinary action is not warranted, he
    or she shall notify the Inspector General with jurisdiction over
    the department or agency concerned and shall provide the Inspector
    General with the reasons for such determination.
      (g) Improper Disclosure Is Violation. - Any willful disclosure or
    use by an investigative or law enforcement officer or governmental
    entity of information beyond the extent permitted by section 2517
    is a violation of this chapter for purposes of section 2520(a).
