Abstract.
Let N be a finitely generated normal subgroup of a Gromov hyperbolic group 
.
We establish criteria for N to have solvable conjugacy problem and be conjugacy separable in
terms of the corresponding properties of 
. We show that the hyperbolic group
from F. Haglund's and D. Wise's version of Rips's construction
is hereditarily conjugacy separable. We then use this construction to produce
first examples of finitely generated and finitely presented conjugacy separable groups that contain
non-(conjugacy separable) subgroups of finite index.
Keywords: Hereditary conjugacy separability; normal subgroups of hyperbolic groups; Rips's construction
