How do I know if my business has a "dominant market position" legally?

Dominance is determined by your "market share" in a specific sector, though having a high share isn't illegal on its own—only abusing it is. In the United Kingdom, you are generally presumed to hold a dominant position if your market share exceeds 40% , whereas in the United States, the threshold for establishing "monopoly power" under the Sherman Act is typically much higher, often requiring a share above 70% . Lawyers will argue over the definition of your "relevant market"—such as whether you dominate the entire "soft drink" market or just the "premium cola" niche—because a narrower definition artificially inflates your market share and increases your legal risk.

Do I need a lawyer to get regulatory approval for a merger?

Yes, because if your deal exceeds certain financial thresholds, reporting it to the government is mandatory, and failing to do so is a "gun-jumping" violation that triggers massive fines. In the United States, under the Hart-Scott-Rodino (HSR) Act, you must file for approval if the deal value exceeds $126.4 million (2025 threshold) , while in the United Kingdom, the Competition and Markets Authority (CMA) has jurisdiction if the target company has a turnover over £70 million or if the merger creates a 25% share of supply . A lawyer ensures you file these complex notices correctly to avoid having the government force you to unscramble the deal after it closes.

What is "predatory pricing" and how can a lawyer defend against it?

Predatory pricing occurs when a dominant company intentionally sets prices below cost to drive competitors out of business, with the plan to raise prices later to recover the losses. To defend you, a lawyer often uses the "recoupment test," particularly in US courts, which argues that the market is so competitive that you could never actually "recoup" those losses by raising prices later. If you can prove that you wouldn't be able to make the money back, the law views your low prices as aggressive competition that benefits consumers rather than illegal predation.

Can a lawyer help if my company is accused of price-fixing?

Yes, and speed is your only friend here because lawyers use "Leniency Programs" to save your company. In both the US and UK, the first member of a cartel to confess to regulators (like the DOJ or CMA) typically receives 100% immunity from fines and jail time, while the second company to confess gets significantly less. A lawyer’s primary job in this crisis is to race your competitors to the regulator's door to secure that "first-in-line" immunity marker, turning you into the witness rather than the primary target.

What are the legal rules regarding exclusive distribution agreements?

Exclusive deals, where you promise to sell products only to one distributor in a region, are generally legal unless your company is powerful enough to distort the market. Under the "Vertical Block Exemption" rules in the UK, these agreements are automatically considered safe as long as both the supplier and the buyer have a market share below 30%. If your market share exceeds that 30% threshold, a lawyer must perform a detailed self-assessment to ensure the contract doesn't illegally lock out competitors, as the automatic legal safety net no longer applies.

How does a lawyer conduct a competition law compliance audit?

A lawyer conducts a compliance audit by acting like a government investigator, raiding your own company to identify risks before the real regulators do. They meticulously review internal emails, Slack messages, and sales strategy documents, searching for dangerous "trigger words" like "stabilize prices," "agree with competitor," or "share the market." They also scrutinize your involvement in trade association meetings, which are a common trap where innocent industry networking can accidentally turn into illegal information exchanges about future pricing strategies.

What should I do if my business is raided by competition authorities (Dawn Raid)?

If regulators like the FBI or CMA show up unannounced, you must follow a strict protocol: never obstruct them, as that is a criminal offense, but immediately call your lawyer and ask the inspectors to wait (usually 30–60 minutes) for counsel to arrive. While you wait, assign staff members to "shadow" every single inspector, writing down every file they examine and making a duplicate copy of every document or hard drive they seize. This ensures that once they leave, your legal team knows exactly what evidence the government has and can prepare your defense accordingly.

Competition FAQ

They are essentially the same legal concept, just with different regional names and slight enforcement variations. "Antitrust" is the term used in the United States (named after the "trusts" like Standard Oil that were broken up in the 1900s), while "Competition Law" is used in the United Kingdom, EU, and most other nations. While both aim to prevent monopolies and unfair trade, US Antitrust law tends to be more aggressive about criminalizing individual executives (sending them to jail), whereas UK Competition law focuses primarily on massive corporate fines, which can reach up to 10% of global turnover.
