Abstract
Recently we proposed that the acceleration of the Universe could be due to gravity leaking to extra dimensions. This scenario gives an alternative to the cosmological constant or quintessence. In [astro-ph/0106274] the authors claimed that this proposal is strongly disfavored if not ruled out by the existing data on Supernovae, Cosmic Microwave Background and clusters. We show that the work [astro-ph/0106274] contains incorrect statements in the theoretical part, and, moreover, we argue that the main conclusions of the work concerning the comparison with the data are premature.
