Government regulation has a deep impact on companies’ operations and is an outsized variable in business planning.  State and federal regulatory and enforcement actions, in courts and before the agencies themselves, can impose significant costs, preempt opportunities, and even endanger a company’s—or a whole industry’s—existence. Eimer Stahl’s former high-ranking state government officials, administrative-law specialists, and regulatory counselors help clients navigate government-facing legal thickets in Washington and across the country. Our team also has extensive experience representing government entities themselves—from agencies and commissions to executive officials and legislative bodies—in regulatory and constitutional disputes.  Whatever the matter, our lawyers are keenly aware that, while litigation is sometimes necessary, often the best approach is to work with the relevant agency to resolve problems.  In any event, and regardless of the forum, regulatory lawyers must know the bedrock principles of administrative law, and our team knows them well.
