Input: Consider Input: Question: How had long had it been since ground was broken at Yucca Mountain nuclear waste repository when Garland dissented in In re Aiken County? Passage:Garland has tended to favor deference to regulatory agencies. For example, in In re Aiken County (2013), Garland dissented when the court issued mandamus ordering the Nuclear Regulatory Commission to process the Yucca Mountain nuclear waste repository license. In Americans for Safe Access v. Drug Enforcement Administration (2013), Garland joined a divided court upholding the DEA's classification of marijuana as a Schedule I drug. However, according to Goldstein, in a number of split decisions on environmental law Garland "favored contested EPA regulations and actions when challenged by industry, and in other cases he has accepted challenges brought by environmental groups." In Rancho Viejo, LLC v. Norton (2003), Garland found the arroyo toad was protected by the federal Endangered Species Act. Then-Circuit Judge John Roberts dissented from the denial of rehearing en banc, writing that Congress's interstate commerce power cannot reach "a hapless toad that, for reasons of its own, lives its entire life in California."
