Abstract
The quasigroup approach to the conservation laws (Phys. Rev. D56, R7498 (1997)) is completed by imposing new gauge conditions for asymptotic symmetries. Noether charge associated with an arbitrary element of the Poincaré quasialgebra is free from the supertranslational ambiquity and identically vanishes in a flat spacetime
