in a number of administrative and educational circumstances. Jayewardene also eliminated a major Tamil grievance by abrogating the "standardization" policy of the United Front government, which had made university admission criteria for Tamils more difficult. In addition, he offered many top-level positions, including that of minister of justice, to Tamil civil servants. While TULF, in conjunction with the UNP, pressed for the all-party conference, the Tamil Tigers escalated their terrorist attacks, which provoked Sinhalese backlash against Tamils and generally precluded any successful accommodation. In reaction to the assassination of a Jaffna police inspector, the Jayewardene government declared an emergency and dispatched troops, who were given an unrealistic six months to eradicate the terrorist threat. The government passed the Prevention of Terrorism (Temporary Provisions) Act in 1979. The act was enacted as a temporary measure, but it later became permanent legislation.
