The one-year tenure had previously been a hindrance, especially for officers at the Inspector level, as frequent transfers prevented them from becoming familiar with their jurisdictions, thereby impacting the efficiency of law enforcement, crime detection, and intelligence gathering.

However, some officers, particularly in Bengaluru, managed to stay in preferred postings for extended periods, which could lead to the development of vested interests.

The amendment aims to strike a balance by providing stability for officers while ensuring that they gain experience in both urban and rural areas.

The government is also tasked with addressing the issue of officers who have remained in specific posts for too long, despite the political influence they may wield.
