On Tuesday afternoon, the plaintiffs in Coons v. Geithner filed their "Reply in Further Support of their Motion for Summary Judgment and in Response in Opposition to Defendants' [Motion] for Summary Judgment." This is the case pending in the District Court for the District of Arizona (District Judge G. Murray Snow) challenging both the minimum essential coverage provision and the breadth of the ACA's legislative delegation to the Independent Payment Advisory Board (IPAB). The United States' reply brief is due September 12, at which point the summary judgment briefing in case will be complete.
