In view of the recent measurement of reactor mixing angle $\theta_{13}$ andupdated limit on $BR(\mu \to e \gamma)$ by the MEG experiment, we re-examinethe charged lepton flavor violations in a framework of supersymmetric type IIseesaw mechanism. Supersymmetric type II seesaw predicts strong correlationbetween $BR(\mu \to e \gamma)$ and $BR(\tau \to \mu \gamma)$ mainly in terms ofthe neutrino mixing angles. We show that such a correlation can be determinedaccurately after the measurement of $\theta_{13}$. We compute different factorswhich can affect this correlation and show that the mSUGRA-like scenarios, inwhich slepton masses are taken to be universal at the high scale, predicts $3.5\lesssim BR(\tau \to \mu \gamma)/BR(\mu \to e \gamma) \lesssim 30$ for normalhierarchical neutrino masses. Any experimental indication of deviation fromthis prediction would rule out the minimal models of supersymmetric type IIseesaw. We show that the current MEG limit puts severe constraints on the lightsparticle spectrum in mSUGRA model if the seesaw scale lies within$10^{13}$-$10^{15}$ GeV. It is shown that these constraints can be relaxed andrelatively light sparticle spectrum can be obtained in a class of models inwhich the soft mass of triplet scalar is taken to be non-universal at the highscale.
