Since the Bhutanese Citizenship Act of 1985 and subsequent Immigration Act of 2007, immigration policy and procedure have been implemented by the Lhengye Zhungtshog (Council of Ministers), Ministry of Home and Cultural Affairs, Department of Immigration. Procedural safeguards for both naturalization and bona fide citizenship remained largely absent: applicants could be rejected for no reason at all, such decisions were final and binding, and even bona fide Bhutanese citizens faced deprivation of citizenship for sedition. Placement and maintaining one's placement in the national census registry is of central importance to legitimizing and proving one's citizenship. Placement by government workers into census registry categories, which ranged from "Genuine Bhutanese" to "Non-nationals: Migrants and Illegal Settlers," has been arbitrary, and could be arbitrarily changed. In some cases members of the same family have been, and still are, placed in different categories. Furthermore, only the entries recorded at the "Dzongkhag" (second highest) level are deemed valid; official local "Dungkhag", "Gewog", "Chewog" or other civil records are disregarded. Under the latest Immigration Act of 2007, department-level immigration officers were given a mandate, and left wide discretion, to enter private premises; examine documents, persons, and things; seize items; and arrest persons. These officers are immunized under the 2007 Act for all wrongful acts and omissions committed in good faith in the discharge of their duty.
