Garda reservists will be barred from policing areas where family members run pubs, betting shops, or any business that requires a court licence to operate, it has emerged.
The regulations governing the proposed 4,000-strong force have been distributed by Minister for Justice Michael McDowell to the Opposition and Garda representative bodies.
The new volunteer officers, who will be required to serve four hours a week, are also to be barred from policing their "immediate neighbourhood", as defined by local senior officers.
The creation of the new force is still opposed by the Garda Representative Association and the Association of Garda Sergeants and Inspectors, though the bodies are to hold further talks with the Minister.
Candidates will be refused membership of the force if they run pubs, bookmakers, dance halls, auctioneering practices, or hold any other licence granted by the courts "involving gain to the holder".
However, the Minister and the Garda Commissioner have gone further by deciding to bar reservists from policing any area where any member of their family holds any such licence.
"A reserve member shall disclose any such interest to the district officer in the district to which the reserve member is allocated," the regulations, seen by The Irish Times, say.
Soldiers, court staff, prison and probation officers, solicitors, summons servers, and private security officers are also to be barred from applying for membership of the new force.
People aged between 18 and 57 will be able to apply to join the reservists, though former gardaí will be able to do so until they are 60.
All will have to retire at 65. Former gardaí will be entitled to apply for the reservists as long as they have received an "exemplary", "very good" or "good" discharge reference from An Garda Síochána.
The new force will be open to membership by any EU national and citizens from Norway, Iceland, Liechtenstein - which are members of the European Economic Area - and Switzerland.
Nationals from other countries will be able to apply for membership if they have lived in the State continuously for one year, and for four of the previous eight years before they submit an application, and if they have worked without the need for a work permit.
Reservists will only be able to patrol if they are accompanied by full-time gardaí, and they will only enjoy the use of their powers when in uniform, and not during the rest of their civilian life.
Recruits must have received a Leaving Certificate grade "not lower than B3 at Foundation Level or D3 at another level in mathematics", and a grade in Irish and English "not lower than C3 at Foundation Level or D3 at another level".
Each recruit will serve two years' probation, though the Commissioner can end his or her service with 30 days' notice. Equally, reservists will be able to quit with 30 days' notice.
