  Let $Y_{1},\dots,Y_{l}$ be smooth irreducible projective curves and let $Y$
be its disjoint union. Given a semisimple reductive algebraic group $G$ and a
faithful representation $\rho:G\hookrightarrow \textrm{SL}(V)$ we construct a
projective moduli space of $(\underline{\kappa},\delta)$-(semi)stable singular
principal $G$-bundles with generalized parabolic structure of type
$\underline{e}$. In case $Y$ is the normalization of a connected and reducible
projective nodal curve $X$, there is a closed subscheme coarsely representing
the subfunctor corresponding to descending bundles. We prove that the descent
operation induces a birational, surjective and proper morphism onto the
schematic closure of the space of $\delta$-stable singular principal
$G$-bundles whose associated torsion free sheaf is of local type
$\underline{e}$.
