Let H and K be quasiconvex subgroups of a negatively curved locally extended ลฝ . residually finite LERF group G. It is shown that if H is malnormal in G, then the double coset KH is closed in the profinite topology of G. In particular, this is true if G is the fundamental group of an atoroidal LERF
