What did the court decide in Rotkiske v. Klemm?
Answered for: US
We hold that, absent the application of an equitable doctrine, the statute of limitations in § 1692k(d) begins to run on the date on which the alleged FDCPA violation occurs, not the date on which the violation is discovered.
The Court held that the FDCPA's one-year limitations period runs from the date of the violation, not the date the consumer discovers it. The sentence above is the court in its own words.
This answer is true in US and nowhere else on this site. Another jurisdiction is another answer, or an honest gap: see what has been read for US.
