Compacts` approaches to their management are different. Some pacts, especially those that set specific conditions for their purpose, may simply designate the agencies of the states that are parties to the Covenant and are responsible for complying with those conditions.  Where meaningful coordination and communication between states is required, a pact may designate one or more persons per state who are responsible for monitoring the state`s performance under the Covenant.  Other compacts may assign important regulatory powers and expertise to intergovernmental organizations to achieve compact objectives and manage compliance.  These intergovernmental organizations can also promote cooperation and serve as essential sources of information on the theme of the Pact.   Virginia v. Tennessee, 148 U.S. 503, 519 (1893). This could happen if a pact « changed the balance of power between the federal states and the federal government, » created coalitions of states that would reduce the power of the federal government or change the balance of power between states in the federal structure, or assert themselves poorly on a constitutionally established subject available to Congress. Buenger et al., supra note 2, at 69. While historically, intergovernmental pacts have included only states as parties, the federal government has recently participated in some pacts.
 Indeed, some Pacts require a representative of the federal government to participate in compact governance. For example, the Woodrow Wilson Bridge and the Compact Tunnel require that a member of the 13-member board of directors governing the pact be appointed by the U.S. Secretary of Transportation, as noted above.  Some pacts have been implemented by Congress under federal law and provide for direct federal involvement in matters involved in the pact, such as the Interstate Agreement on Detainers, which applies to the transfer of prisoners convicted of independent trials. The date of congressional approval is not set in the Constitution, so approval can be given either before or after state approval of a particular pact. Consent may be explicit, but it can also be inferred from the circumstances. Congress may also set conditions for approving a pact.  Congress must explicitly approve any pact that would increase the political power of states in a way that would bring down the power of the federal government.  Decision-making procedures in a compact are defined in the compact itself.
