  We consider the dynamics invariant under the action of l-conformal Galilei
group using the method of nonlinear realizations.
  We find that by an appropriate choice of the coset space parametrization one
can achieve the complete decoupling of the equations of motion. The Lagrangian
and Hamiltonian are constructed. The results are compared with those obtained
by Galajinsky and Masterov [Nucl. Phys. B860, (2013), 212].
