MN HF34

Expands Minnesota antitrust law to prohibit monopsony power (single-buyer market control) alongside existing monopoly prohibitions, and eliminates procompetitive effects as a defense to antitrust violations

Prohibits "unconscionably excessive" pricing, defined as charging more than 10% above the average price for the same or similar good/service in the affected area during the prior 30 days or compared to other purchasers in the trade area

Bans price discrimination between different purchasers of like commodities when the effect lessens competition or tends to create a monopoly/monopsony, with exceptions for cost-based differentials and meeting competitor prices

Increases civil penalties significantly: up to $100,000 per violation for individuals, up to $5,000,000 per violation for corporations with revenue exceeding $10,000,000, and up to $250,000 for failing to comply with court judgments

Modifies statute of limitations to begin when violations are discovered (or should have been discovered) rather than when they occurred, and makes aiding/abetting antitrust violations a separate offense
