Motion to transfer denied.
In the case challenging the termination of the Solar for All program in federal district court for the Western District of Washington, the court denied the federal defendants’ motion to transfer the case to the federal district court for the District of Columbia where an <a href="https://www.climatecasechart.com/document/harris-county-v-epa_25df">earlier lawsuit</a> had been filed by Harris County, Texas. The court found that “first-to-file” factors weighed against transfer, noting the differences between the parties in each case and the fact that a <a href="https://www.climatecasechart.com/document/rhode-island-afl-cio-v-epa_b8da">third case</a> had been filed in the District of Rhode Island before Harris County v. EPA was filed. In addition, the court found that factors of convenience and fairness were either neutral or leaned against transfer.
