Bloch et al. [Phys. Rev. C 60, 062201 (1999)] presented a calculation of the electromagnetic form factors of the nucleon using an ansatz for the quark-diquark solution of the relativistic three-quark Faddeev equation. In this Comment it is pointed out that the calculation of these form factors stems from a three-quark bound state current that contains overcounted contributions. The corrected expression for the three-quark bound state current is derived.
