The issue before the court is whether a member of the Florida House of Representatives and his aide are entitled to claim legislative privilege as a ground for refusing to testify in a civil case. A legislative privilege existed under the common law, and we conclude that it continues to apply in Florida by general legislation adopting the common law. We also conclude that a legislative privilege is implicit in the separation of powers provision of the Florida Constitution. Because the testimony to be given in this case is within the scope of the privilege, we hold that the subpoenas at issue must be quashed.
The controversy over the existence of a legislative privilege arose from two tax cases, both of which are pending in the circuit court for Leon County. In these cases, Expedia and other online travel companies filed complaints against Bro-ward County and Osceola County to challenge the assessment of tourist development taxes. The counties filed counterclaims alleging, among other things, that the travel companies had evaded their obligations to pay the taxes.
In the course of related tax litigation in Georgia, Expedia was ordered to produce certain internal documents, including written communications prepared by its law firm and its accountants. These documents were confidential but they were disclosed to opposing counsel in the Georgia *520 litigation under a protective order. Subsequently, the lawyer for Broward County came into possession of the documents and sought to use them as evidence in the Florida cases. The trial court ruled that the documents were privileged and that they would not be admissible in evidence, in the absence of a showing that Expedia had waived the privilege.
Meanwhile, the Florida Legislature was considering a bill that would have afforded favorable tax treatment to hotel bookings made by Expedia and other online travel companies. Rick Kriseman, a member of the Florida House of Representatives, opposed the bill. The lawyer for Broward County provided Representative Kriseman with the Expedia documents that were to remain confidential under the terms of the Georgia protective order. Representative Kriseman then forwarded the documents to all of the members of the Florida House of Representatives and made them available, as well, to certain members of the press.
Following the dissemination of the documents, the lawyers for Expedia obtained subpoenas directing Representative Krise-man and his aide, David Flintom, to appear for depositions. They wanted to ask these two men how they obtained the documents. The Florida House of Representatives moved to quash the subpoenas on the ground that Representative Kriseman and his aide were protected by legislative immunity. Expedia argued that the testimony to be elicited was necessary to prove that it had not provided the documents independently of the lawyer for Broward County, and thereby to establish that it had not waived the privilege protecting the documents.
The trial court denied the motion to quash in part and held that the depositions could go forward on a limited basis. The court ruled that the lawyers for Expedia could ask Representative Kriseman and Mr. Flintom whether Expedia or any of its agents had independently provided the documents at issue. In that event, the lawyers could ask Representative Krise-man and Mr. Flintom what they had done with the documents once they received them. The court emphasized the narrow scope of the permissible inquiry and stated that no questions could be asked pertaining to the thoughts, opinions, or legislative activities of the witnesses.
The House of Representatives filed a petition for writ of prohibition in this court on behalf of Representative Krise-man and his aide, to prevent the trial court from going forward with the depositions. We treat the petition for writ of prohibition as an appeal from a final order. See Fla. R.App. P. 9.040(c) (stating that “[i]f a party seeks an improper remedy, the cause shall be treated as if the proper remedy had been sought”).
Prohibition does not lie if the party seeking relief has an adequate remedy by appeal.
See Sparkman v. McClure,
*521
Our conclusion that the order is appeal-able is directly supported by the precedent set in
Calderbank v. Cazares,
This court reached the same result in
Transcall America, Inc. v. Butterworth,
In the present case, there is no ongoing proceeding between the parties to the lawsuit and the individuals who have been ordered to provide discovery. As to these individuals, the order is final.
See Smith v. State,
We begin our analysis on the merits of the appeal by observing that the Florida courts have not yet directly held that a member of the state legislature is entitled to claim a testimonial privilege. The subject was discussed in
Girardeau v. State,
Although the issue has not been squarely addressed in Florida, there is ample authority in American law for the proposition that a member of the legislative branch has a right to assert a legislative privilege. The testimonial privilege that protects a legislator from the command of a subpoena issued in a civil case is closely related to the immunity that protects a legislator from civil liability. These protections are based on the same *522 policy considerations. As we shall explain, the privileges and immunities afforded to all government officials, including those who serve in the legislative branch, arise from the common law.
The principle of legislative immunity was so well established in English and American law that it was incorporated into the United States Constitution. In the leading case of
Tenney v. Brandhove,
The
Tenney
case dealt with immunity from suit, but the Supreme Court subsequently held in
Gravel v. United States,
The Florida Constitution does not include a version of the Speech or Debate Clause, but the decisions in
Tenney
and
Gravel
are significant to our analysis, nonetheless. These decisions illustrate that the Speech or Debate Clause is based on legislative privileges and immunities that are firmly rooted in the common law. As the Supreme Court explained in
Ten-ney,
“The privilege of legislators to be free from arrest or civil process for what they say or do in legislative proceedings has taproots in the Parliamentary struggles of the Sixteenth and Seventeenth Centuries.”
Tenney,
The Speech or Debate clause is limited by its terms to members of Congress, yet the court in
Tenney
applied the underlying common law principles to conclude that members of the California Legislature were immune from liability in a civil suit. Subsequently, the Court extended legislative immunity to local legislative officials,
see Bogan v. Scott-Harris,
The principles that give rise to the need to immunize legislators are the same as those that justify immunity for members of other branches of government. Judges are immune from suit,
see Pierson v. Ray,
This common law principle is most often used to immunize a judge from liability in civil litigation, but it has also been used to support the proposition that a judge cannot be compelled to testify about his or her thought process in making a decision in a case.
See State v. Lewis,
We can draw the same analogy to the protections afforded to public officials in the executive branch of the government, as these protections are also based on the common law. In
Spalding v. Vilas,
Additionally, as with their counterparts in the judiciary and the legislature, public officials in the executive branch are entitled to a testimonial privilege.
See United States v. Nixon,
It is clear from these authorities that the privileges and immunities protecting all public officials, including members of the legislature, arise from the common law. The significance of this point is simply this: if legislative privileges and immunities existed under the common law, they continue to exist, apart from specific constitutional provisions like the Speech or Debate Clause, to the extent that a state continues to recognize the common law.
Section 2.01, Florida Statutes, provides in material part that “[t]he common law and statute laws of England which are of a general and not a local nature ... are declared to be of force in this state; provided, the said statutes and common law [are] not inconsistent with the Constitution and laws of the United States and the acts of the Legislature of this state.” It follows from this language that if legislative immunity existed under the common law of England, it continues to exist in Florida. Because we know of no law abrogating the common law on this point, we conclude *524 that Florida legislators continue to enjoy legislative immunity under state law.
As an independent ground for our decision, we conclude that legislative privilege exists by virtue of the separation of powers provision of the Florida Constitution. This constitutional issue is closely related to the common law issues we have discussed. One purpose of common law legislative immunity was to protect the independence of the legislature. Another purpose was to “reinforce the separation of powers” between the branches of government.
Fowler-Nash v. Democratic Caucus of Pa. House of Representatives,
Article II, section 3 of the Florida Constitution states, “The powers of the state government shall be divided into legislative, executive and judicial branches. No person belonging to one branch shall exercise any powers appertaining to either of the other branches unless expressly provided herein.” The importance of this provision cannot be overstated. Our supreme court described the separation of powers as “the cornerstone of American democracy.”
Bush v. Schiavo,
We suggested in
Girardeau
that the separation of powers provision in Article II, section 3 would support a claim of legislative privilege.
Girardeau,
Because the right to assert a legislative privilege arises from the state constitution as well as the common law, it is among those privileges that exist independently of the Florida Evidence Code. Section 90.501, Florida Statutes limits the testimonial privileges that are available to those that are listed in the Evidence Code. Legislative privilege is not listed in the Code but it falls within the exception for those privileges that “arise from the Constitution of the United States or of the State of Florida.” See § 90.501, Fla. Stat. Because it arises from the separation of powers provision in Article II, section 3, as we have explained, it continues to exist notwithstanding the fact that it is not among the testimonial privileges identified in the Code.
Although there is no judicial precedent in Florida for legislative immunity, there is no reason why we should not now recognize that it exists. Nor do we see any reason why this form of immunity, like the others, should not also include a privilege that can be asserted against the obligation that would otherwise exist to give compelled testimony in a civil case. In Gravel, the United States Supreme Court treated legislative testimonial privilege as a necessary incident of the legislative immunity it had previously recognized in Tenney, and we believe the same logic applies here. If legislators are immune from civil liability for actions taken in the course of their legislative duties, they are also entitled to refuse to testify about the performance duties.
*525
This leads us to the question of whether the testimony to be elicited in the present case falls within the scope of the privilege. We conclude that it does. The documents that are the subject of the inquiry were acquired and distributed in the course of a debate within the House of Representatives on the merits of a pending bill. Gathering information pertaining to potential legislation and sharing it with colleagues is an essential part of the legislative process. Thus, it is clear that Representative Kriseman and his aide were performing a legitimate legislative function.
See Kamplain v. Curry County Bd. of Comm’rs,
Furthermore, we have little doubt that the privilege may be asserted by legislative staff members as well as the legislators themselves. The reason for affording a legislative privilege could be subverted entirely if an aide could be forced to disclose that which the senator or representative would be entitled to keep private.
See Gravel,
The legislative privilege we have recognized in this case is not absolute. On this point, we adhere to our decision in Girardeau that the privilege could not be used to withhold evidence of a crime. An absolute testimonial privilege is not available even to the President of the United States. See United States v. Nixon, supra The court will always have to make a preliminary inquiry to determine whether the information is within the scope of the privilege and whether the need for privacy is outweighed by a more important governmental interest.
No such interest has been demonstrated in the present case. Expedia claims that it needs to ask whether the documents were provided to Representative Kriseman by any of its own agents. This is a curious question, given the fact that the parties acknowledge that the documents were in fact provided by the lawyer for Broward County. Nevertheless, Expedia claims that it is necessary to prove that it did not provide the documents independently, so that it can refute a claim that it had waived the attorney-client privilege with respect to the documents. The problem with this claim is that the burden of proving a waiver is on the counties. Expedia is attempting to refute a fact that has not yet been proven and, as it appears from this record, may never be proven.
In summary, we hold that Representative Kriseman and Mr. Flintom are entitled to assert a legislative privilege. Because the questions to be asked of them regarding the documents they received and the actions they took in connection with a bill pending in the legislature are within the scope of the privilege, they cannot be compelled to testify. For these reasons, we reverse with instructions to quash the subpoenas.
Reversed.
