What is the responsibility of a Preliminary Inquiry Officer?

The role of a Preliminary Inquiry Officer is primarily focused on collecting facts related to an alleged offense. This involves investigating the circumstances and gathering evidence to determine whether there is sufficient information to warrant further action in the military justice process. The Preliminary Inquiry Officer's responsibilities are crucial because they help establish the basis for any potential charges and ensure that the subsequent proceedings are based on accurate and comprehensive information. By systematically documenting findings, the officer aids in maintaining a fair and just approach within the military judicial environment.

The other responsibilities outlined in the choices pertain to different roles within the military justice system. For example, assigning military justice penalties typically falls under the purview of a commanding officer or a court-martial, while providing legal defense for accused members is the responsibility of a designated defense counsel. Overseeing ceremonial duties does not relate to the operational aspects of military justice and is often the responsibility of other personnel focused on unit morale and tradition.
