Kinder v. Geithner is the case currently pending in the Eighth Circuit. The District Court for the Eastern District of Missouri dismissed the plaintiffs' complaint (opinion here) on the ground that none of the plaintiffs had established an injury in fact sufficient to sustain Article III standing. The plaintiff-appellants filed their brief just over a month ago (available here). On Monday, two amicus curiae briefs were filed at the Eighth Circuit in support of the plaintiffs.
* A brief on behalf of Texas, Florida, Alabama, Alaska, Arizona, Colorado, Georgia, Idaho, Louisiana, Maine, Michigan, Nebraska, Nevada, North Dakota, Ohio, Pennsylvania, South Carolina, South Dakota, Utah, Washington, and Wisconsin (authored by Paul Clement, counsel to the states in Florida v. HHS), which is available here.
* A brief on behalf of 154 state executive and legislative officials from states within the Eighth Circuit (which comprises Arkansas, Iowa, Minnesota, Missouri, Nebraska, North Dakota, and South Dakota), which is available here.
The United States's brief as appellee is due August 11.
