Each of our lawyers is cross-trained in all areas of antitrust law, which allows us to provide seamless counseling to clients across:
- Pre-merger notification and substantive defense of transactions;
- Every type and stage of government investigation, including cartels;
- Wide range of civil and criminal antitrust litigation;
- State aid awards; and
- General counseling, antitrust audits, and compliance programs.
