One when Roberts involved Microsoft, and the other involved strip mining in W VA.
Contrary to claims that Roberts is in the pocket of "big business,"3 in his capacity as a partner with Hogan & Hartson, he represented the 19 states that joined the federal government in suing Microsoft.4
Roberts represented a coal company before the Supreme Court in a case where the coal company sought to discharge an employee truck driver for repeated drug abuse.5 The case was litigated because an arbitrator twice found that the employee’s repeated drug use was not "just cause" to terminate his employment.6 Such arbitration was part of the company’s contract with the union but the company wanted the arbitrator’s decision overturned as a clear violation of "public policy."7 Justice Souter stated that in order for the Court to break a contractual agreement using "
he force of public policy" the public policy "has to be very very clear."8 Roberts argued that public policy of keeping drug-impaired drivers off of the nation’s highways was crystal clear.9 However, the Court reluctantly found for the employee with Justice Breyer conceding that "e recognize that reasonable people can differ as to whether reinstatement or discharge is the more appropriate remedy here."10
