Resolution 1540 requires states to "promote the universal adoption and full implementation, and, where necessary, strengthening of multilateral treaties to which they are parties, whose aim is to prevent the
proliferation of nuclear, biological or chemical weapons" (Article 8a) and to "fulfil their commitment to multilateral cooperation, in particular within the framework of the
International Atomic Energy Agency, the
Organisation for the Prohibition of Chemical Weapons, and the
Biological and Toxin Weapons Convention" (Article 8c). Although the resolution encourages and promotes universal
WMD treaty implementation, states not yet a party retain their prerogative not to sign these treaties. The focus of Resolution 1540 is not the treaties per se but the resulting national legislation and regulations that allow to take action against non-state actors. States will have gone a long way toward complying with the resolution if they have already ratified the three main
WMD treaties, but the reverse is also true. If States put the required national legislation in place to comply with UNSCR 1540, then becoming state party of and complying with the
Chemical Weapons Convention and the
Biological and Toxin Weapons Convention will not demand much additional effort. In this way the resolution also contributes to treaty universality. Resolution 1540 tries to fill gaps in the varying approaches of existing instruments. First of all, the resolution is universal unlike the three main
WMD treaties. Whereas the three main WMD treaties, the
Non-Proliferation Treaty, the
CWC and the
BTWC are first and foremost applicable to states, the resolution focuses on
non-state actors. Because individuals are not subject to
international law, states are required to ensure a national legal framework of laws, regulations and controls. Third, unlike the
IAEA to the
NPT and the
OPCW to the
CWC, there exists no such organization to the
BTWC. Similarly, for the
means of delivery, there only exists a regime so these delivery systems are not the subject of legally binding
non-proliferation treaties. Resolution 1540 explicitly integrates proliferation concerns about these means. The resolution goes beyond the three main
non-proliferation treaties and specifies in article 2 and 3 the additional measures required concerning financial, security, and physical protection of sensitive materials and also border and export controls. Lastly, the Resolution, adopted under
Chapter VII of the United Nations Charter, requires enforcement. This emphasizes the role states are expected to play to pre-empt
proliferation (article 10), because it hints at the possibility of
sanctions in case of non-compliance. It also tries to address the enforcement weakness in the treaties and export control regimes.
Nuclear weapons Resolution 1540 has a complementary relationship to the
NPT and the
IAEA. The IAEA has activities and programs that are relevant to the implementation of the resolution 1540 such as legislative assistance, training of state officials, support to states in the development and implementation of physical protection of nuclear material and facilities and support to states to upgrade border controls in order to better detect illicit trafficking of
nuclear material and related technology. The
1540 Committee can inform states about requesting legislative and technical assistance and advisory services from the IAEA. The IAEA does not only cover
nuclear material but also
radioactive material, the latter is of special interest to
non-state actors, because it would be easier to obtain. Another useful tool provided by the IAEA is their Incident and Trafficking Database (ITDB).
Chemical weapons The
CWC and its mandated organization the
OPCW face new challenges in a changing international WMD context which Resolution 1540 aims to remedy. An important obligation of the CWC is the adoption of appropriate national implementing legislation, but even after the adoption of an action plan by the OPCW to encourage state parties to rectify this situation, many states parties fail to meet this obligation. Comprehensive national implementing legislation is not only necessary to fully meet the obligations to the CWC, but it is vital in preventing
non-state actors from gaining access to chemical weapons and UNSCR 1540 has rendered it a mandatory requirement. Although the CWC has an effective verification regime by international inspectors of the OPCW, this may not always be the case when faced with
non-state actors if there exists no national legislation that grants easy access to private residences. The resolution also addresses the question of "related materials". Its definition includes chemicals and equipment covered by multilateral arrangements and national control lists such as the
Australia Group, the
Proliferation Security Initiative and the EU’s strategy against the proliferation of WMD, and is thus much broader than the three schedules of chemicals in the Annex of the CWC. In addition
non-state actors can already cause serious damage with amounts that are far below those that are considered militarily significant and states should consider this in their actions to counteract the preparation or use of chemical weapons by those actors.
Biological weapons As said before, the
BTWC has no organization to oversee its implementation and lacks an effective monitoring,
compliance and
verification regime. There exists a modest consultative compliance mechanism, but negotiations to establish an international organization for the prohibition of biological weapons to oversee implementation and conduct monitoring and verification have broken down in 2001. The lack of transparency make it difficult to assess the status and effectiveness of states parties' measures to implement and comply with the BTWC. UNSCR 1540 has established a monitoring system based on states' declarations on implementation through the reports provided to the
1540 Committee. The resolution does not provide a compliance regime, but rather favors cooperative efforts since non-compliance can be caused by lack of awareness or capacity. But if states persist in their non-compliance despite assistance, then the committee will report this to the
UNSC. Resolution 1540 also fulfills a function compliance role since it requires BTWC states parties to review their compliance with its obligations while they can use the more detailed criteria for national implementation in the resolution.
Means of delivery UNSCR 1540 promotes a greater understanding of non-proliferation instruments related to means of delivery such as the
Missile Technology Control Regime (MTCR). Up to the adoption of the resolution export control measures related to means of delivery had not been discussed widely in the international community. The MTCR is an informal and voluntary association that aims to control the proliferation of rockets and
unmanned air vehicle systems. Resolution 1540 requires as one of the measures that states maintain effective export controls and although every country can implement the arrangements according to its national legislation, this legislation is now mandatory. Since the principal focus of the resolution are
non-state actors, means of delivery are expected to be less sophisticated means. The risk of
non-state actors obtaining sophisticated
ballistic or
cruise missile technologies continues to exist and the Resolution will have to take into account the
dual-use technologies in its implementation so as not to affect legitimate peaceful commercial uses and industrial research. ==Application==
