In April Mr Obama named Craig Becker, a law professor and lawyer for the Service Employees International Union, to one of three vacancies on the five-member National Labour Relations Board (NLRB), whose decisions weigh heavily on the balance of power between unions and management. Business groups are furious. In a joint letter sent to Congress on October 20th, they protested that Mr Becker’s views are “well outside the mainstream and would disrupt years of established precedent and the delicate balance in current labour law.”
Mr Bush’s appointees to the NLRB systematically voted against labour.
This is a lot like saying the intent to uphold existing environmental regulation is "well outside the mainstream and would disrupt years of established precedent and the delicate balance in current environmental law." It's only true to the degree that not enforcing the law can be ever be called a "precedent."
