The sensitivity to the invisible decay of the mass eigenstate ν 3 in the presence of Earth matter effects is studied. Only the charged current interactions of atmospheric ν µ andν µ for 500 kTon year exposure of a future magnetised iron detector at INO are analysed. The analysis with observed muon energy in the range would give a constraint of τ 3 /m 3 > 1.51 × 10 −10 s/eV at 90% CL with this exposure. Here τ 3 is the lifetime and m 3 is the mass of ν 3 , when it is the heaviest. The effect of
