  The decays $\bar{B}\to \bar{K}D$ and $\bar{B}\to \bar{K}\bar{D}$ taking into
account final state interactions are discussed. These decays are described by
four strong phases $\delta_0, \delta_1, \tilde{\delta}_0, \tilde{\delta}_1$
(subscript 0 and 1 refer to I=0 and I=1 isospin final states), one weak phase
$\gamma $ and four real amplitudes. Isospin constraints are taken into account.
It is argued that strong interaction dynamics gives $\delta_1\approx
\tilde{\delta}_1$. The four real amplitudes are estimated. Some observable
consequences are discussed.
