We comment on the papers "Nucleon elastic form factors and local duality" [
Phys. Rev. D 62, 073008 (2000)] and "Experimental verification of quark-had
ron duality" [Phys. Rev. Lett. 85, 1186 (2000)]. Our main comment is that t
he reconstruction of the proton magnetic form factor, claimed to be obtaine
d from the inelastic scaling curve thanks to parton-hadron local duality, i
s affected by an artifact.
