**Black holes and symmetries in Chern-Simons AdS gravity**

We analyze spherically symmetric, static black hole solutions in 5D Chern-Simons AdS gravity with electric charge introduced through a U(1) extension of AdS group. We discuss different static black hole solutions of this theory that appear in the literature. Then we find the most general spherically symmetric, electrically charged solution, expected to contain all other solutions as particular cases. However, we discover that our ansatz possesses less physical degrees of freedom than expected. This happens due to appearance of “accidental” local symmetries in the chosen region of phase space of the theory.
