When the Trump administration instituted worldwide tariffs using emergency powers, we told the Supreme Court that the president can’t impose tariffs without congressional authorization and that the administration is using a fake emergency to try to get around the Constitution’s separation of powers. In oral arguments, some of the justices echoed the arguments in our brief.

When the Department of Justice sued Maine, Michigan, and New York to demand private voter data in an effort to undermine our elections, we filed motions to intervene on behalf of voters. States have the right to protect their citizens’ data.

When the administration invoked the Alien Enemies Act to carry out mass deportations, we supported successful litigation challenging the illegal use of this wartime power. As the litigation moves through the appeals process, we’ll continue to fight this overreach and advocate for everyone’s right to due process.

When the administration attempted to single-handedly rewrite election rules by requiring people to produce a passport or a similar document to vote, we partnered with allies to sue — and scored a decisive victory.
