We consider the 2D incompressible Euler equation on a corner domainwith anglewith. We prove that if the initial vorticityand ifis non-negative and supported on one side of the angle bisector of the domain, then the weak solutions are unique. This is the first result which proves uniqueness when the velocity is far from Lipschitz and the initial vorticity is nontrivial around the boundary.
