The combin.d in.luen.es of Hall cur.en.s an. r.tation.on.the MHD Couette flow of a viscous in.ompr.ssible electr.cally con.uctin. fluid between.two in.in.te hor.zon.al par.llel por.us plates chan.el in.a r.tatin. system in.the pr.sen.e of a un.for. tr.n.ver.e magn.tic field have been.car.ied out. The solution. for.the velocity field as well as shear.str.sses have been.obtain.d for.small time as well as for.lar.e times by Laplace tr.n.for. techn.que. It is foun. that for.lar.e times the Hall cur.en.s acceler.tes pr.mar. flow wher.as it r.tar.s secon.ar. flow while the r.tation.r.tar.s the pr.mar. flow wher.as it acceler.tes the secon.ar. flow. It is also foun. that the velocity compon.n.s con.er.e mor. r.pidly for.small time solution.than.the gen.r.l solution. The asymptotic behavior.of the solution.is an.lyzed for.small as well as lar.e values of magn.tic par.meter.M2, r.tation.par.meter.K2 an. r.yn.lds n.mber.r.. It is obser.ed that a thin.boun.ar. layer.is for.ed n.ar.the movin. plate of the chan.el an. the thickn.sses of the layer.in.r.ases with in.r.ase in.either.Hall par.meter.m or.r.yn.lds n.mber.r. while it decr.ases with in.r.ase in.Har.man. n.mber.M. It is in.er.stin. to n.te that for.lar.e values of M2 , the boun.ar. layer.thickn.ss is in.epen.en. of the r.tation.par.meter.
