Abstract
We investigate the possibility of constructing a locally supersymmetric extension of nonsymmetric gravitation theory (NGT), based on the graded extension of the Poincaré group. In the framework of the simple model that we propose, we end up with a no-go result, namely the impossibility of cancelling out some linear contribution in the gravitino field. This drawback seems to seriously undermine the construction of a supergravity based on NGT.
