  Flavour-violating couplings of Higgs boson with stop and scharm quarks could
be very important as in addition to lifting the mass of the Higgs boson by a
few GeV, it could also play a vital phenomenological role in reducing the
Supersymmetry breaking scale significantly. In this work, we investigate
effects of such flavour-violating couplings within the Constrained Minimal
Supersymmetric Standard Model (CMSSM) framework in the context of LEP data,
Higgs data at the LHC, precision observables and the relic density of the dark
matter using Bayesian statistics. Our detailed analysis reveals that the most
probable values of $m_{0}$, $m_{1/2}$, $A_{0}$, $\tan{\beta}$,
$\delta^{LR}_{ct}$ are expected to be around 4.83 TeV, 2.54 TeV, 1.90 TeV,
41.5, and 6.1$\times10^{-2}$, respectively, with flat priors. The corresponding
values translate into 3.25 TeV, 2.13 TeV, 1.90 TeV, 44.7, and
5.9$\times10^{-2}$, respectively, if the natural priors are used. Furthermore,
a comparison of our model with the CMSSM of flavour-conservation as the base
model yields a Bayes factor of about 6 while taking into account all the
experimental constraints used in our study. Our analysis also reflects that the
lightest neutralino would have a mass of about 1 TeV.
