Nonacquiescence
In law, nonacquiescence is the intentional failure by one branch of the government to comply with the decision of another to some degree. It tends to arise only in governments that feature a strong separation of powers, such as in the United States, and is much rarer in governments where such powers are partly or wholly fused. In the context of lawsuits, executive nonacquiescence in judicial decisions can lead to bizarre Kafkaesque situations where parties discover to their chagrin that their legal victory over the government is an empty one. Nonacquiescence can also possibly lead to a constitutional crisis, given certain critical situations and decisions.
