An obvious method of compliance is the creation of cooperation agreements that would not constitute „agreements or pacts“ within the meaning of the constitutional prohibition. If they have powers under their own laws, states are free to enter into „non-binding“ agreements beyond their borders. The guidelines for coordination between the United States and Mexico on epidemiological events of common interest are not binding and serve as an example for this type of approach.19 Non-binding agreements can be useful to states, especially when they are interested in the exchange of information. In response to the growing recognition of the importance of mutual assistance agreements, the Public Health Law Program of the Centers for Disease Control and Prevention has made efforts to characterize the legal framework for mutual assistance. In particular, the programme collected information on mutual assistance and related laws for the categories of intergovernmental and international mutual assistance, systematically established and synthesized information, conducted basic complementary legal research, and evaluated and identified legal approaches to achieving effective mutual assistance. These efforts included meetings, follow-up and participation in the activities of several groups that participated, at the national level, in projects to improve state mutual assistance to other states or against other states in Mexico and Canada. Intergovernmental cooperation is made possible and facilitated by the objective of provisional national preparedness set out under Directive 8 on internal security, which sets as a national priority broader regional cooperation through mutual assistance agreements (Table 1▶). The cooperation agreements concluded by the Centers for Disease Control and Prevention, which aim to improve and improve public and local health care, promote the development of mutual assistance agreements as a preparatory instrument. Finally, Congress provided funding and instructed the DHHS Secretary to: 13 Although the DHHS Health Resources and Services Administration funds esAR-VHP development, states are responsible for the design, development and▶ management of what is intended as a national system of national emergency volunteer registry. Cross-border cooperation is an obvious part of the system. The Pandemic and All-Hazard Prevention Act, Public Law 109-417, is a new and important addition to the federal structure of mutual aid. A consortium of states may be considered an eligible agency under the law, and Section 201 requires „a description of the mechanism that the company will implement for the use of the Emergency Management Support Pact or any other mutual assistance agreement for medical and public assistance.“ These provisions, along with other provisions of the Mutual Assistance Agreements Act for the implementation of federal, national, local and tribal coordination and resource integration between these agencies, are strong evidence of the encouragement of mutual aid agreements by Congress. In general, utility companies also have mutual assistance agreements.
 Given that States conclude that their existing laws allow for entry into mutual aid agreements or if they pursue new laws to obtain such power, a concerted effort should be made to share and make the most of the knowledge acquired between states.
