No, the law is not always valid.
it is valid only in closed and isolated systems, in an open system some mass can be converted to energy and escape the system so the resultant mass will be less and the law will be violated. Secondly, in nuclear reactions where energy is involved, the mass converts into energy - therefore as in the first case, the resultant mass will be less.
The violation of this Law was removed by Einstein who redefined it as mass-energy relation
