Why might an interested party sue to block a policy's implementation?

An interested party may choose to sue to block a policy's implementation primarily because they believe the policy conflicts with other laws. This concern typically arises when a new policy may infringe upon established legal standards, regulations, or rights that have been upheld by previous legislation or judicial decisions. Legal conflicts can encompass a wide range of issues, from constitutional rights to statutory regulations, and when a policy is perceived to violate these legal frameworks, stakeholders often resort to litigation as a means to seek redress. The judicial system acts as a check on policy implementation, ensuring that all laws and policies are in compliance with the legal standards of the jurisdiction. This process is fundamental in maintaining the rule of law and upholding the rights of individuals or organizations that may be adversely affected by the new policy.
