Then send him/her this decision from 2010 which was MY first Google result when checking into it - the decision of the court was BASED on the ruling from 38 years ago.
But as I edited my initial post to say, I did find conflicting information on the subject. Some courts rule it's ok, some rule it's not. If you dig you'll find both.
The point of the 38 year old decision is that it is not what CONGRESS intended, as Title III was intended to deal with combating organized crime not domestic disputes. It further states that domestic matters in the home should be governed by STATE level statutes not FEDERAL ones.
Did you finish reading your own link? I really don't mean to make waves here man, but the simpson case doesn't sean to hold much precedant at all anymore.
Despite the Simpson ruling, the majority of circuits have denied that any marital exception exists in the Wiretap Act. The Fourth, Sixth, Eighth, Tenth, and Eleventh Circuits have extended wiretapping actions to interspousal parties. In fact, the Eleventh Circuit’s 2003 Glazner v. Glazner decision expressly overruled Simpson. There, the court found no “implied exception” to the Wiretap Act “for interspousal wiretapping within the marital home.” The court stressed the statute’s express language permitting “any person” whose communications are intercepted to bring a civil action. The court deemed Mrs. Glazner such “any person” under the statute and asserted there should be “no distinction between married and unmarried persons or between spouses and strangers.” The court also maintained that since the Fifth Circuit decided Simpson three decades ago, most courts have similarly declined to find a spousal exception to the Wiretap Act. The concurring opinion added “Simpson was a badly reasoned decision rejected by virtually every other circuit to consider it.”
