	Introduction

Through its investigative powers, Congress gathers information it considers necessary to oversee the implementation of existing laws or to evaluate whether new laws are necessary. When Congress finds an inquiry blocked by the withholding of information, or where the traditional process of negotiation and accommodation is considered inappropriate or unavailing, a subpoena—either for testimony or documents—may be used to compel compliance with congressional demands. An individual—whether a member of the public or an executive branch official—has a legal obligation to comply with a duly issued and valid congressional subpoena, unless a valid and overriding privilege or other legal justification permits non-compliance. The subpoena, however, is only as effective as the means by which it is potentially enforced. Without a process by which Congress can coerce compliance or deter non-compliance, the subpoena would be reduced to a formalized request rather than a constitutionally based demand for information. Congress currently employs an ad hoc combination of methods to combat non-compliance with subpoenas. The two predominant methods rely on the authority and participation of another branch of government. First, the criminal contempt statute permits a single house of Congress to certify a contempt citation to the executive branch for the criminal prosecution of an individual who has willfully refused to comply with a committee subpoena. Once the contempt citation is received, any later prosecution lies within the control of the executive branch. Second, Congress may try to enforce a subpoena by seeking a civil judgment declaring that the recipient is legally obligated to comply. This process of civil enforcement relies on the help of the courts to enforce congressional demands. But legislative leverage and the subpoena enforcement mechanisms do not always ensure congressional access to requested information, particularly from the executive branch. Recent controversies could be interpreted to suggest that the existing mechanisms are at times inadequate—at least in the relatively rare instance that enforcement is necessary to respond to a current or former executive branch official who has refused to comply with a subpoena. In any event, any attempt by Congress to mandate that the executive branch initiate a specific prosecution, including a prosecution for criminal contempt of Congress, has been opposed by the executive branch and may raise constitutional questions. The executive branch continues to assert the position that inter-branch oversight disputes are non-justiciable. Alternative Subpoenas Enforcement Frameworks

There would appear to be several ways in which Congress could alter its approach to enforcing committee subpoenas issued to executive branch officials. Federal law had provided for expedited judicial review of lawsuits filed by the Senate to enforce subpoenas. If either the House or Senate was to revive the inherent contempt power, the chamber may consider establishing specific procedures to be followed in its exercise.
Congress gathers much of the information necessary to oversee the implementation of existing laws or to evaluate whether new laws are necessary from the executive branch. While executive branch officials comply with most congressional requests for information, there are times when the executive branch chooses to resist disclosure.
When Congress finds an inquiry blocked by the withholding of information by the executive branch, or where the traditional process of negotiation and accommodation is inappropriate or unavailing, a subpoena—either for testimony or documents—may be used to compel compliance with congressional demands. The recipient of a duly issued and valid congressional subpoena has a legal obligation to comply, absent a valid and overriding privilege or other legal justification. But the subpoena is only as effective as the means by which it may be enforced. Without a process by which Congress can coerce compliance or deter non-compliance, the subpoena would be reduced to a formalized request rather than a constitutionally based demand for information.

But these mechanisms do not always ensure congressional access to requested information. Recent controversies could be interpreted to suggest that the existing mechanisms are at times inadequate—particularly in the instance that enforcement is necessary to respond to a current or former executive branch official who has refused to comply with a subpoena. There would appear to be several ways in which Congress could alter its approach to enforcing committee subpoenas issued to executive branch officials. These alternatives include the enactment of laws that would expedite judicial consideration of subpoena-enforcement lawsuits filed by either house of Congress; the establishment of an independent office charged with enforcing the criminal contempt of Congress statute; or the creation of an automatic consequence, such as a withholding of appropriated funds, triggered by the approval of a contempt citation. In addition, either the House or Senate could consider acting on internal rules of procedure to revive the long-dormant inherent contempt power as a way to enforce subpoenas issued to executive branch officials. Yet, because of the institutional prerogatives that are often implicated in inter-branch oversight disputes, some of these proposals may raise constitutional concerns.
