The Dodd-Frank Wall Street Reform Act has generated more work for lawyers and lobbyists since being signed into law than during even the frenzied days leading up to its passage in the House and Senate last summer. That’s because a host of federal regulatory agencies are now in the process of trying to write the rules that will turn the law into reality. Work has begun on drafting 243 rules and on 67 separate studies by the likes of the Treasury Department, the Securities and Exchange Commission, the Commerce Department, the Commodities Futures Trading Commission and other regulatory agencies, according to one estimate by the law firm Davis Polk & Wardwell.
