The 1988 convention follows closely the basic approach and principles adopted by several previous conventions dealing with international terrorism. Like all these instruments, the 1988 convention aims at suppressing acts of violence specifically defined therein through extended jurisdictional bases for the apprehension of offenders and the mechanism of extradition or prosecution under national procedures, thus depriving the offenders of safe havens in any of the states parties. The convention follows the basic pattern of most of the preceding instruments for the suppression of terrorist activities. It has, however, adopted a few improvements on the previously introduced concepts and mechanisms, particularly the inclusion of bodily injuries and killing of a person among the offenses and the delivery of offenders by the ship's masters. The system does not contain an obligation to extradite, and extradition is subject to the conditions stipulated by the law of the requested state. In case there are concurrent requests for extradition, the system allows the requested state the discretion to choose the state to which it prefers to extradite the suspect. The system does not contain an absolute obligation to prosecute and punish the offender. It merely obligates the states to submit the case to the competent authorities for the purpose of prosecution through proceedings in accordance with their law. 51 notes
