Section 4B provides four years from accrual, which occurs when the defendant commits an act injuring the plaintiff's business. Fraudulent concealment and the continuing violation doctrine extend the period.
Government suits toll private actions.
Alternative Names:
Antitrust Limitations Period|Clayton Act Limitations
Why it Matters?
Government enforcement tolls private limitations during the proceeding and for one year afterward, which is why follow-on civil actions filed years after the conduct remain timely, and calculating the tolled period requires identifying when the government action commenced and concluded. The continuing violation doctrine separately restarts accrual with each overt act causing new injury, which sustains claims in ongoing conspiracies.
