Jirga is a Persian word meaning gathering, a public, a "Punchayat" or a consultation. To Marree, Baloch, Pukhtoon, Tajak, Hazara and Shin tribes, the literal meaning of Jirga is a traditional institution which seeks solutions to their economic, social, cultural, regional and defence problems under their social and cultural system by integrated consultation and collective participation such as arrangement of regional defence; issuance of traditional laws; check and balance; distribution, arrangement and utilization of resources and distribution of labour etc.

It becomes known from their administrative and defensive approaches that, in order to cope with external attacks or defence, Palas people have a traditional post of the Zetu who keeps them united and dynamic during tough times of defending the land. He is responsible for planning against external dangers and for defensive matters through mutual consultations. A Zetu is appointed for a certain period and for a specific purpose and he has the support of all the tribes and groups. This position is neither permanent nor is there a need to announce his termination. After the purpose is met, the position comes to an end or suspension by itself or at the time of appointing a Zetu, his term is fixed and well explained. If seen from the perspective of the regional defence, their council is established during tough conditions relying on a clan and a "zetu" is chosen from this same council.

The role of a Zetu was observed under the conditions of sending local people's army (lashkar) in 1996. He can be viewed as holding a position of a war commander (Sipah Salar). In Shina folk poetry, the war rhythms, that are locally called "Bigai wazan" (the rhythms played during an exchange of gun-fire), are reflective of it.

A Zetu manages the shortages of food, arms and warriors while a Kalak does not do these jobs, keeps an eye on the defence of the "Rom" and its survival while a Jashtero tries to keep his personal reputation. The cultural activities make a Jashtero and to a Zetu the responsibilities of defence and maintenance of unity are entrusted. In other words, what is achieved by the efforts of both is that a Jashter's earning is for the sake of his own name and a Zetu's earning is for the sake of the whole "Rom". When 12 Zetus from both the group or 24 Zetus in total, are elected, the Zetus together elect one more person from each group who is called "Qesgar" (the conceiver of a solution to an issue in case of a disagreement between the parties). It is their responsibility that if there is a disagreement between these 24 Zetus on any issue, they solve it justly. Those two conceivers elect a third person who is called "Munsif" (the judge). His responsibility is to make a final settlement of the issue which could not be resolved by the Zetus and the two conceivers, because in certain matters, the group interests are associated making it hard for people to agree. Since in Bar Palas(Daro), Darma are found (in majority), their Zetus are elected from among the clans of Sorma, Phirie, Derkhana and Bhoei Mugla. There is no Zetu of Khuka Manka here because their economical interests are based with the Kuz Palas.

In the past few years, one new position has been introduced here in comparison to a Zetu which is called a Committee Member. The Government has assigned these positions to certain people to get support. However, there is a big contradiction between the status of a Committee member and the role of a Zetu.
