Business groups have already begun to take aim at President Obama’s recess appointments. As SCOTUSBlog reports, a coalition of industry groups filed a motion (and supplementary memorandum) to include a challenge to the constitutionality of President Obama’s recess appointments to the National Labor Relations Board in ongoing litigation against recently adopted “notice posting” rule. According to the industry groups, the NLRB lacks the authority to implement and enforce the new rule because it lacks a quorum due to the unconstitutionality of the recent appointments.
