Query: Comment on "Chern-Simons theory and atypical Hall conductivity in the
  Varma phase''   In a recent paper published in this Journal [Phys. Rev. B 97, 075135 (2018)],
Menezes et al. analyze the topological behavior of a effective bosonic model
defined on the Lieb lattice in presence of an electromagnetic field. In this
context, the authors claim to have found an atypical quantum Hall effect for
the quasiparticles. However, some inconsistencies related to the treatment of
the propagator jeopardizes the main result in this system.
