When sufficient numbers of holes are introduced into the two-dimensional CuO2 square lattice, dynamic magnetic correlations become incommensurate with underlying lattice in all previously investigated La_2\ensuremath-xAxCu_1\ensuremath-zBzO4+y ( A\phantom\rule0ex0ex=\phantom\rule0ex0exSr or Nd, B\phantom\rule0ex0ex=\phantom\rule0ex0exZn) including high Tc superconductors and insulators, and in bilayered superconducting YBa2Cu3O6.6 and Bi2Sr2CaCu2O8. Magnetic correlations also become incommensurate in structurally related La2NiO4 when doped with Sr or O. We report an exception to this so-far well-established experimental ``rule'' in La2Cu_1\ensuremath-zLizO4 in which magnetic correlations remain commensurate.
