It is argued that the "quadratic Sagnac effect" recently put forward by G B Malykin and V I Pozdnyakova is the consequence of an incorrect estimation of second order relativistic corrections and not a real physical phenomenon. The correct expression for the phase shift induced by rotations in a Michelson interferometer is presented.
