  In the classical relativistic regime, the accretion of phantom-like dark
energy onto a stationary black hole reduces the mass of black hole. Here we
have investigated the accretion of phantom energy onto a stationary charged
black hole and have determined the condition under which this accretion is
possible. This condition restricts the mass to charge ratio in a narrow limit.
This condition also challenges the validity of the cosmic censorship conjecture
since a naked singularity is eventually produced as magnitude of charge
increases compared to mass of black hole.
