Abstract
The aim of this Comment is to call to the attention of double special relativity (DSR) readers a basic fact. The introduction of noncommutative structures in problems like the one addressed by Ghosh [ Phys. Rev. D 74, 084019 (2006)] is not necessary for the understanding of DSR physics. It can be described just as the relativistic free particle problem in a different parametrization.
