The paper analyses the Rayleigh-Taylor instability of a viscous compressible rotating fluid through a porous medium in a vertical magnetic field. It is shown that the system is characterized by a variational principle and by making use of it, a solution is obtained for a layer having exponential density along the vertical. The dispersion relation has been obtained by employing the normal mode technique and solved numerically. It is found that the kinematic viscosity, rotation and permeability of the porous medium have a stabilizing and compressibility has a destabilizing influence on the growth rate of the unstable mode of disturbance.
