The duties and virtues inherent in the Buddhist religious law (dharma) played a large role in the legal code, which remained in force until the 1960s.
Considered a special type of Buddhist literature, these codes have a close connection with, but are separate from, the general vinaya rules on individual morality and conduct.
[10] While they shared some common elements of basic structure, individual Tsa Yig codes vary considerably in scope and content, such that no one could be called typical.
The Tsa Yig for one gelugpa establishment provides, "when itinerant game hunters appear, they should be punished by gathering their weapons in the protector's temple and in addition exhorted once again to observe lawfulness.
In 1902, for example, the laws of the Tsa Yig were observed written on a broad sheet of pasted daphne paper and posted in a conspicuous position in a Tibetan Bönpo monastery.
The Tsa Yig stipulated that when an ordained monk was found guilty of violating rules, particularly those regarding chastity, he should be immediately punished and expelled from the monastery.
Such punishments were, however, commutable into fines, such as the payment of money to the lama who ordained him, and providing entertainment and presents for the other monastic authorities and the members of the congregation.
[12] The Tsa Yig held a special position in Bhutan as the nation's main legal code from its founding in 1629, through the establishment of the modern Bhutanese monarchy, until de jure abrogation in 1965.
The Tsa Yig of Shabdrung Ngawang Namgyal laid down the dual system of government of Bhutan, a synthesis of spiritual and temporal authority.
Soon after ascension to the throne and office, the king found it necessary to make several modifications to the existing Tsa Yig, citing "dangerous laxity" as having "crept into all branches of justice.
"[13] The grandson of Ugyen, King Jigme Dorji Wangchuck further reformed the Tsa Yig as part of his broader modernization program.
In modern Bhutan, village heads often judged minor cases and Dungkhag (district) officials adjudicated major crimes.
