In addition, the statute creates a cause of action for private individuals whose communications were unlawfully monitored. The statute permits actual damages of not less than $1,000 or $100 per day. In addition, that statute authorizes punitive damages and an award of attorney's fees. Similar liability is found under the subchapter pertaining to physical searches. In both cases, the statute creates an affirmative defense for law enforcement personnel acting within their official duties and pursuant to a valid court order. Presumably, such a defense is not available to those operating exclusively under presidential authorization.
