In this work we will study the longitudinal polarisations of both leptons in the decay process (B) over bar -> (K) over bar (2)(1430)l(+)l(-). This process has all the features of the related and well investigated process (B) over bar -> (K) over bar*(890_l(+)l(-), with theoretically comparable branching ratios. The polarised differential decay rates as well as the single and double polarisation asymmetries are worked out, where the sensitivity of these to possible right-handed couplings for the related b -> s radiative decay (and other BSM parameters) are also investigated.
