It's basically the standard argument that multiple quasiparticle descriptions of the same theory can be given. The linked notes on Jordan-Wigner work out an example in gory detail, but this same thing shows up wherever quasiparticles are used.
I guess you also need to think through some stuff about the way preparation and measurement apparati work - how you couple the experimenter in & out of the system. I'm not sure I've ever seen the whole picture written out together in a publication.
