We use the language of exterior differential forms and the properties of Majorana spinors on 3-dimensional space-times to explicitly demonstrate the local supersymmetry of the action density involved. Exact coupled field equations that are complete in both of their bosonic and fermionic sectors are derived by a first order variational principle subject to a torsion-constraint imposed by the method of Lagrange multipliers. Cotton and Cottino 2-forms that are complete to all orders in the gravitino field are derived and their properties such as trace are investigated.pdfPhysicsJournal Article1521-3978https://doi.org/10.1002/prop.202100009652191900001Q2NOIR02956
