Abstract: This paper is devoted to the leading twist exclusive bottomonia decays withdouble charmonium in the final state. Using models of the twist-2 charmoniadistribution amplitudes the widths of these decays are calculated within lightcone formalism. In addition, the processes under consideration are studiedwithin nonrelativistic QCD. In our analysis we have found that the productionof some of the $P$-wave charmonia mesons with $L z eq 0$ is allowed alreadyat the leading twist approximation. This means that the selection rules whichpredict the suppression of such decays are violated. The mechanism which liesbehind this violation is discussed.
