In Nakar & Piran (2004) we have shown that a large fraction of BATSE bursts\ncannot satisfy the Amati relation between the isotropic energy - peak energy of\nGRBs. Our results have been corroborated by a further analysis carried out by\nBand and Preece (2005). Recently Ghirlanda et al. (2005) claimed that when the\nexact distribution of the scatter around the Amati relation is taken into\naccount, the BATSE sample is consistent with the Amati relation. We show that\nthe probability that the BATSE sample is consistent with the Amati relation\n(including the scattering), as found by Ghirlanda et al. (2005) for a sample of\n23 bursts with known redshift, is vanishingly small.\n
