Hello,
HR is a staff function, i.e., a "support function." Making things happen is a line function. HR has no authority over the "line," and therefore, it should only play an "advisory role." It is the personality of the concerned HR that perhaps makes him interfere in the line function. This could be happening with the best of intentions but should be curbed, just as it could be happening with "power-mongering" motivations to impose self-importance.
One must know the intentions before sitting in judgment or initiating any "corrective" actions. Unless one has all the facts and has taken an objective view of the matter and issues, it would vitiate the organizational atmosphere. Unless you share more facts and state the purpose of your query, I am afraid you are unlikely to receive correct advice.
Regards,
