  We derive the off-shell nilpotent and absolutely anticommuting
Becchi-Rouet-Stora-Tyutin (BRST), anti-BRST and (anti-)co-BRST symmetry
transformations for the Christ--Lee (CL) model in one (0 + 1)-dimension of
spacetime by exploiting the (anti-)chiral supervariable approach (ACSA) to BRST
formalism where a few specific and appropriate sets of invariant quantities
play a decisive role. We prove the nilpotency and absolute anticommutativity
properties of the (anti-)BRST and (anti-)co-BRST conserved charges within the
framework of ACSA to BRST formalism where we take only one Grassmannian
variable into account. We also show the (anti-)BRST and (anti-)co-BRST
invariances of the Lagrangian within the framework of ACSA.
