In this paper we critically examine recent claims about half metallic ferromagnetism in open p-shell systems.
Odd valence electron compounds like CaAs have been predicted to show a 100 % spin polarization
at the Fermi level, if they can be grown in the zincblende structure. It has furthermore been argued that
this should be possible under special conditions. We will give several arguments against this claim based
on concepts from chemistry and density functional calculations.
