Plaintiffs appeal as of right the trial court’s grant of summary disposition for defendants on the basis of governmental immunity in this action for invasion of privacy, malicious prosecution, and intentional infliction of emotional distress. We affirm in part and reverse in part.

Plaintiff Paul Gracey was a candidate in the August 1989 election for the office of municipal judge in the City of Grosse Pointe Farms. His wife, plaintiff Irene Gracey, hand-delivered a number of absentee ballots to the city clerk’s office although she was not a member of the immediate family of *415these voters. There were no allegations that plaintiffs engaged in fraud with respect to these absentee ballots.

The day before the primary election, the Michigan State Police were contacted about plaintiffs’ conduct. James Killeen, the Wayne County Clerk, called a press conference at which he alleged improprieties on the part of plaintiffs. Plaintiffs alleged that Killeen, the Wayne County Board of Canvassers, and Edward Carey, the Elections Director for Wayne County, knowingly gave false information at the press conference concerning plaintiff Irene Gracey’s involvement in the election process. Plaintiffs also alleged that these defendants knowingly gave false information to the police. Plaintiffs alleged that defendant John D. O’Hair, the Wayne County Prosecutor, continued to prosecute plaintiff Irene Gracey after this Court had found that she had not tampered with any absentee ballots. Finally, plaintiffs alleged that Wayne County was vicariously liable.

Plaintiffs argue that actions of a county clerk that might normally be considered within the scope of authority of the clerk become acts outside that scope when performed for an ulterior purpose. We agree. A motion for summary disposition pursuant to MCR 2.116(C)(7) should not be granted unless no factual development could provide a basis for recovery. Harrison v Director of Dep’t of Corrections, 194 Mich App 446, 449; 487 NW2d 799 (1992). In order to determine whether plaintiffs’ alleged facts justify a finding that recovery in tort is not barred by governmental immunity, a court must consider all affidavits, pleadings, depositions, admissions, and documentary evidence filed or submitted by the parties. Id.

Plaintiffs claimed that Killeen was a neighbor and financial contributor to one of plaintiffs’ oppo*416nents, Eugene Casazza. Casazza allegedly informed Killeen that plaintiff Irene Gracey had violated election laws with regard to absentee ballots. Plaintiffs claimed that Killeen did nothing until the eve of the primary election and then called a press conference to announce that there was an illegal handling of ballots by Irene Gracey, thus tainting the election. It is plaintiffs’ claim that the allegations made by Killeen were false and that the press conference was called for the sole purpose of swaying the electorate by dissuading voters from supporting Paul Gracey. Gracey was defeated in the election.

The trial court recognized that Killeen "may very well have had ulterior motives and probably did, but the fact that he had ulterior motives does not take away his function as county clerk and him performing his task as county clerk.”

We believe that the Supreme Court in Marrocco v Randlett, 431 Mich 700, 713; 433 NW2d 68 (1988), reintroduced concepts that define governmental function by reference to an actor’s intent. Consequently, if defendant intentionally conducted a press conference to cause some mischief not authorized by law, then his otherwise appropriate action is not the exercise of a governmental function and is outside the scope of his immunity. In Ross v Consumers Power Co (On Rehearing), 420 Mich 567, 592; 363 NW2d 641 (1984), the Supreme Court stated:

Judges, legislators, and the highest executive officials of all levels of government are absolutely immune from all tort liability whenever they are acting within their respective judicial, legislative, and executive authority.

The county clerk qualifies as one of the highest *417executive officials in county government. Thus, county clerks are absolutely immune if they are acting within their executive authority. However, no case attempted to define "within their executive authority” until Marrocco, supra, p 707. Marrocco analogizes the determination of "executive authority” to the determination of a "governmental function” utilized when reviewing the acts of lower level officials. Id., p 708. The Marrocco majority suggested that the highest executive officials are acting within their executive authority only if they are engaging in an activity that expressly, or by necessary implication, is authorized by constitution, statute, or other law. Id., p 708, ns 6, 7, and 8.

The Marrocco Court specifically emphasized, quoting Smith v Dep’t of Public Health, 428 Mich 540, 544, 611; 410 NW2d 749 (1987), that the intentional use or misuse of a badge of governmental authority for a purpose unauthorized by law is not the exercise of a governmental function. Id., pp 707-708.

As pointed out in the concurring opinion of Justice Boyle, the majority in Marrocco appears to have adopted the position that the tortious nature of the defendants’ act may, in and of itself, carry the act outside the official’s executive authority and thereby outside the scope of his immunity. Thus, here, even if the county clerk expressly or impliedly possessed authority to conduct a press conference, Marrocco suggests that if the county clerk’s purpose in holding the press conference was not authorized by law, then the county clerk was not acting within the scope of his executive authority, and he is not entitled to absolute immunity.

We believe that it is a mistake to tamper with the clear, broad concept of absolute immunity as *418expressed in Ross. However, we are bound by Supreme Court precedent and reluctantly conclude that Marrocco has reintroduced concepts that define executive authority by reference to the actor’s intent. Until the Supreme Court gives further direction or clarification, we presume that there is an intentional-tort exception to governmental immunity for the intentional use or misuse of a badge of governmental authority for a purpose unauthorized by law. Therefore, assuming that Killeen had the authority to call a press conference to address any improprieties that might have occurred during an election, he nevertheless had no authority to conduct a press conference for the purpose of disseminating false information with the intent to sway an election. If that was Killeen’s purpose, as claimed by plaintiffs, then he was not acting within the scope of his executive authority, and he is not entitled to absolute immunity for those acts.

Plaintiffs also argue that summary disposition was inappropriate with respect to defendant Carey because they alleged facts to show Carey’s gross negligence. We disagree that plaintiffs have set forth specific facts to show a genuine issue for trial. In order for plaintiffs to survive Carey’s motion for summary disposition, they must allege facts justifying application of an exception to governmental immunity. Wade v Dep’t of Corrections, 439 Mich 158, 163; 483 NW2d 26 (1992). The governmental immunity act takes great pains to protect government employees to enable them to enjoy a certain degree of security as they go about performing their jobs. Madison v Detroit, 208 Mich App 356, 360; 527 NW2d 71 (1995). In this case, plaintiffs must allege that Carey’s actions amounted to gross negligence, i.e. that his conduct was so reckless as to demonstrate a substantial *419lack of concern for whether an injury would result. Jennings v Southwood, 446 Mich 125, 136; 521 NW2d 230 (1994).

Although plaintiffs’ complaint alleged that Carey requested an investigation into the actions of plaintiff Irene Gracey when Carey knew or had reason to know that the allegations were factually and legally false, Carey averred in an affidavit that he did not request a state police investigation. Plaintiffs have not provided any proof that Carey in fact called for such an investigation. A party opposing summary disposition pursuant to MCR 2.116(0(10) may not rest on mere allegations of a pleading, but must, by affidavits or other appropriate means, set forth specific facts to show that there is a genuine issue for trial. Patterson v Kleiman, 447 Mich 429, 432; 526 NW2d 879 (1994).

Moreover, even if Carey had initiated such an investigation, it was part of his job to oversee election operations in Wayne County. Indeed, the investigation discovered irregularities in the absentee ballot process. No reasonable juror could have honestly concluded that an investigation under these circumstances constituted gross negligence. Accordingly, summary disposition was appropriate. Enzymes of America, Inc v Deloitte, Haskins & Sells, 207 Mich App 28, 34; 523 NW2d 810 (1994).

Plaintiffs argue that this Court’s granting of mandamus to plaintiffs constituted a finding that the Wayne County Board of Canvassers acted outside the scope of its authority. We disagree. Generally, government agencies are immune from tort liability for injuries arising out of the exercise or discharge of a governmental function. MCL 691.1407(1); MSA 3.996(107)(1); Madison, supra, p 359. A governmental function has been defined as "any activity which is expressly or impliedly man*420dated or authorized by constitution, statute, or other law.” Ross, supra, p 591. Here, the Legislature has authorized a board of canvassers in each county to conduct recounts of election results. MCL 168.24a; MSA 6.1024(1). Improper performance of an activity authorized by law is, despite its impropriety, still "authorized” within the meaning of the governmental function test. Richardson v Jackson Co, 432 Mich 377, 385; 443 NW2d 105 (1989). Therefore, defendant here was still cloaked with governmental immunity. Id., p 387.

Plaintiffs also assert that the Wayne County Board of Canvassers can be found grossly negligent. We disagree. The gross-negligence exception to governmental immunity states that it applies to officers, employees, members, or volunteers of governmental agencies. MCL 691.1407(2); MSA 3.996(107)(2). The cardinal rule of statutory construction is to ascertain and give effect to the intention of the Legislature. Jennings, supra, p 135. The exception does not state that it applies to the governmental agencies themselves. Express mention in a statute of one thing implies the exclusion of other similar things. Id., p 142. Elsewhere, this Court held that an exception to governmental immunity applied to governmental agencies where the statute, the since-repealed version of the Emergency Medical Services Act, applied to "persons.” Malcolm v East Detroit, 437 Mich 132, 140; 468 NW2d 479 (1991). Here, had the Legislature intended to include governmental agencies in the gross negligence exception to governmental immunity, it easily could have used the appropriate, general language.

Finally, plaintiffs argue that Wayne County is vicariously liable. However, vicarious liability is derivative. Because the claim against defendant *421Killeen is the only one to survive summary disposition, Wayne County cannot be vicariously liable for the alleged torts committed by the other defendants.

In addition, a governmental agency can be held vicariously liable only when its officer, employee, or agent, acting during the course of employment and within the scope of authority, commits a tort while engaged in an activity that is nongovernmental or proprietary or that falls within a statutory exception. Ross, supra, p 625. Here, the only way Killeen can be held liable is if he was not acting within the scope of his authority. Id., p 592. But, if that is so, Wayne County would not be vicariously liable. Id., p 625.

The trial court’s grant of summary disposition is vacated with regard to defendant Killeen, and affirmed with regard to the other defendants. Remanded for proceedings consistent with this opinion. We do not retain jurisdiction.

(concurring). I agree with the holding of the majority but write separately to express my disagreement with its reluctance in applying the intentional tort exception to governmental immunity found in Marrocco v Randlett, 431 Mich 700; 433 NW2d 68 (1988). I appreciate that the clear, broad concept of absolute immunity is easier for the courts to apply. But, in balance, a remedy must be available to address an intentional use or misuse of governmental authority for a purpose not authorized by law. For that reason, I believe the Marrocco decision was not a mistake, and I apply its holding without reluctance.
