  In this paper, we test the weak cosmic censorship conjecture (WCCC) for the
Reissner-Nordstr\"{o}m-de Sitter (RN-dS) black hole surrounded by perfect fluid
dark matter. We consider a spherically symmetric perturbation on deriving
linear and non-linear order perturbation inequalities by applying new version
of gedanken experiments well accepted from the work of Sorce and Wald. Contrary
to the well-known result that the Reissner-Nordstr\"{o}m (RN) black hole could
be overcharged under linear order particle accretion it is hereby shown that
the same black hole in perfect fluid dark matter with cosmological parameter
cannot be overcharged. Considering a realistic scenario in which black holes
can not be considered to be in vacuum we investigate the contribution of dark
matter and cosmological constant in the overcharging process of an electrically
charged black hole. We demonstrate that the black hole can be overcharged only
when two fields induced by dark matter and cosmological parameter are
completely balanced. Further we give a remarkable result that black hole cannot
be overcharged beyond a certain threshold limit for which the effect arising
from the cosmological constant dominates over the effect by the perfect fluid
dark matter. Thus even for linear accretion process, the black hole cannot
always be overcharged and hence obeys the WCCC in general. This result would
continues be fulfilled for non-linear order accretion.
