Old formulation? Mmm... don't know exactly what that means... but consider this:

The many-body wavefunction must be antisymmetric under interchange of the variables describing any two electrons. This is more general than a description in terms of "orbitals", but of course if an orbital description is possible it forbids two electrons to be in the same orbital.
