[¶ 1] Maietta Construction, Inc., Louis Maietta Sr., Robert L. Maietta, Michael L. Maietta, Louis B. Maietta Jr., Vincent A. Maietta, Thomas S. Maietta, James D. Maietta, Robert D. Maietta, and Neil L. Maietta (Maietta) appeal from a judgment entered in the Superior Court (Cumberland County, Crowley, J.) in favor of Theodore Wainwright dismissing all five counts of Maietta’s complaint alleging defamation, intentional infliction of emotional distress, false light, interference with an advantageous relationship, and requesting punitive damages. Maietta argues that the Superi- or Court erred in finding that (1) the Anti-SLAPP statute, 14 M.R.S.A. § 556 (2003), applies to its claims; (2) there is a basis in fact for Wainwright’s statements; and (3) Maietta was not injured in fact by Wainwright’s statements. Wainwright cross-appeals, arguing that the court exceeded the bounds of its discretion in refusing to award him attorney fees. We disagree with both Maietta and Wainwright and affirm the judgment.
I. BACKGROUND
[¶ 2] This case stems from a grievance concerning a parcel of land, which Wain*1172wright conveyed to the City of South Portland in January 1999. Wainwright had owned a 400-acre potato and turf farm partially located in South Portland. ‘Wainwright sold 150 acres of the property to the City subject to the condition ... that soil or loam could not be removed from the property.” Maietta was awarded a contract to develop the property into a recreational complex for the City. The contract contained terms prohibiting Maietta from removing any topsoil or loam from the property.
[¶ 3] Upon visiting the property, Wainwright became convinced that Maietta was removing loam, in violation of Maietta’s contract with the City, as well as the condition of sale. Wainwright brought his concerns to the City Council, and eventually retained an attorney in the hope of encouraging the City to take action against Maietta’s alleged removal of the loam from the site. Unhappy with the City’s response to his concerns, Wainwright extended his campaign, allowing his attorney to contact local news reporters. This resulted in a series of newspaper articles and television reports about the dispute.
[¶4] Maietta filed suit against both Wainwright and his attorney, David Lour-ie, alleging that they had been defamed by Wainwright’s public campaign accusing Maietta of stealing loam.1 Wainwright and Lourie filed special motions to dismiss pursuant to section 14 M.R.S.A. § 556,2 accompanied with supporting affidavits and exhibits. In their motions they asserted that any statements they made to City officials or the press were solely part of an effort to compel the City to enforce restrictions placed in the deed, as well as the terms of the contract between the City and Maietta.
[¶ 5] The Superior Court found that Wainwright and Lourie had satisfied their burden of asserting that the suit was based on Wainwright exercising his constitutional right of petition. Consequently, the burden shifted to Maietta to show that the Defendants’ petitioning activity lacked “any arguable basis in law,” or lacked any “reasonable factual support.” Morse Bros. v. Webster, 2001 ME 70, ¶ 20, 772 A.2d 842, 849 (quoting 14 M.R.S.A. § 556). The Superior Court held that Maietta had been unsuccessful in showing that Wainwright’s petitioning lacked an arguable basis in fact or law. The Superior Court awarded attorney fees to Lourie, determining that “the Plaintiffs were attempting to intimidate or silence an attorney who was representing a client with potentially legitimate concerns involving property sold with conditions to the City of South Portland.” Conversely, the Superior Court held that there was some merit to Maietta’s claims against Wainwright, and therefore the *1173court refused to award attorney fees to Wainwright.
II. DISCUSSION
[¶ 6] Section 556 was designed to combat “litigation without merit filed to dissuade or punish the exercise of First Amendment rights of defendants.” Morse Bros., 2001 ME 70, ¶ 10, 772 A.2d at 846 (quoting Lafayette Morehouse, Inc. v. Chronicle Publ’g Co., 37 Cal.App.4th 855, 44 Cal.Rptr.2d 46, 48 (1995)). Section 556 targets plaintiffs who “do not intend to win their suits; rather they are filed solely for delay and distraction, and to punish activists by imposing litigation costs on them for exercising their constitutional right to speak and petition the government for redress of grievances.” Morse Bros., 2001 ME 70, ¶ 10, 772 A.2d at 846 (quoting Dixon v. Superior Court, 30 Cal.App.4th 733, 36 Cal.Rptr.2d 687, 693 (1994)). Maietta’s suit was based on the petitioning activity of Wainwright.
A. Special Motion to Dismiss
[¶7] Maietta’s complaint cites letters written by Wainwright or Lourie, addressed to the City Council and the May- or, as well as statements made to the newspapers. These communications clearly amount to petitioning activity. Moreover, contrary to Maietta’s contention, this is the sort of petitioning activity envisioned by the statute. In Morse, we held that the “typical mischief that [section 556] intended to remedy was lawsuits directed at individual citizens of modest means for speaking publicly against development projects.” Morse Bros., 2001 ME 70, ¶ 10, 772 A.2d at 846 (quoting Duracraft Corp. v. Holmes Prods. Corp., 427 Mass. 156, 691 N.E.2d 935, 940 (1998)). Therefore, the trial court did not err in holding that section 556 applied to the facts of this case.
[¶ 8] In Morse Bros., we articulated the standard of review:
We “review the judge’s decision regarding such a special motion to dismiss to determine whether there was an abuse of discretion or error of law. [ ] When reviewing the motion, the Court should view the evidence in the light most favorable to the moving party because the responding party bears the burden of proof when the statute applies.”
Morse Bros., 2001 ME 70, ¶ 18, 772 A.2d at 849 (citations omitted). The Superior Court was required to dismiss Maietta’s complaint unless Maietta could show that there was no reasonable factual basis for Wainwright’s petitioning. 14 M.R.S.A. § 556. Wainwright’s motion for dismissal included affidavits stating that he had personally witnessed Maietta’s employees removing soil from the property. The affidavit also averred that Wainwright had presented the issue to the City Council, but had not received a satisfactory explanation. Wainwright also included in his motion photos that purport to show Maiet-ta employees removing loam. Because this evidence is viewed most favorably to the moving party, it cannot be said that the trial court exceeded the bounds of its discretion by holding that there was enough evidence to conclude that there was “arguably a legitimate basis for Defendant Wainwright to bring his concerns to the attention of the City of South Portland and to the press.”
B. Section 556 Requires Proof of Actual Damages
[¶ 9] Maietta asserts that the trial court erred in concluding that it did not suffer an actual injury based on Wainwright’s petitioning activity. Maietta points out that certain categories of defamation are deemed sufficiently serious that damages are presumed. Hence, Maietta contends that because the allegations, if established, constitute defamation per se, they also constitute actual damages. Maietta misinterprets the actual injury requirement.
*1174 [¶ 10] Maietta is incorrect in suggesting that damages per se are equivalent to actual damages. “Recovery for slander per se requires no showing of special harm beyond the publication itself.” Rippett v. Bemis, 672 A.2d 82, 86 (Me.1996). “When recovery may be had only for actual damage sustained [however] the record must contain evidence from which damage in a definite amount may be determined with reasonable certainty.” Dairy Farm Leasing Co. v. Hartley, 895 A.2d 1135, 1140 (Me.1978) (quoting McDougal v. Hunt, 146 Me. 10, 14, 76 A.2d 857, 860 (1950)). Such a determination “must not be left to mere guess or conjecture.” Id. at 1141. Generally, Legislatures are deemed to draft legislation against the backdrop of the common law, and do not displace it without directly addressing the issue. See Meyer v. Holley, 537 U.S. 280, 285, 123 S.Ct. 824, 154 L.Ed.2d 753 (2003). Therefore, the Legislature imposed the requirements of section 556 understanding that they would require plaintiffs to produce affirmative evidence of an injury.
C. Attorney Fees
[¶ 11] The trial court granted attorney fees to Lourie but not to Wainwright. Wainwright cross-appeals for attorney fees.3 ‘We review the Superior Court’s determination of attorney fees for an abuse of discretion.” Lee v. Scotia Prince Cruises Ltd., 2003 ME 78, ¶ 18, 828 A.2d 210, 215 (citations omitted). The trial court distinguished between Wainwright and Lourie based upon the premise that the lawsuit against Wainwright has more merit than the suit against his attorney, and therefore better conforms to the policy behind the statute. Wainwright contends, as does the dissent, that the distinction between Wainwright and his attorney does not further the statute’s policy, and is not supported by the record. We disagree.
[¶ 12] We note at the outset that the trial court’s use of the merit of the respective cases, as a measure of whether attorney fees are appropriate, is logical because the anti-SLAPP statute is aimed at preventing litigation that has no chance of succeeding on the merits. Morse Bros., 2001 ME 70, ¶10, 772 A.2d at 846 (“SLAPP litigation, generally, is litigation without merit filed to dissuade or punish the exercise of First Amendment rights of defendants.”) (citation omitted).
[¶ 13] The record supports the trial court’s findings with respect to the merit of the suit against Wainwright. The merit of a case is simply its likelihood of success. The determination of merit requires the trial court to weigh the evidence and assess its probative value. The trial court did not exceed the bounds of its discretion in its determination that the case against Wainwright is stronger than the case against Lourie.4 The gravamen of Maiet-ta’s complaint is that Maietta, Inc. has been publicly (and falsely) accused of steal*1175ing, a serious criminal allegation which could irreparably injure its professional reputation.
[¶ 14] While there is direct evidence that Wainwright publicly accused Maietta of stealing loam, it is not clear that Lourie made such an assertion. In a sworn affidavit, Maietta refers to a meeting in August of 2002, during which “Mr. Wainwright accused Maietta Construction of stealing loam [but] provided neither a basis for his accusations nor information evidencing such a claim.” The chronology of events submitted by Jeffrey K. Jordan, South Portland city manager, makes reference to instances in which Wainwright directly (not through his attorney) alleged that Maietta was stealing loam. The record reveals Lourie calling for an investigation, criticizing the City for dragging its heels with respect to an inquiry, and even questioning whether Maietta had removed loam in contravention of the terms of the land grant. While these are serious accusations, they are less likely to support a defamation claim. It was not, therefore, an abuse of discretion for the trial court to conclude that there is less merit to the claim against Lourie, and therefore the suit against him more closely resembles a classic SLAPP suit.
[¶ 15] It should be noted, however, that the varying merit assigned to the cases by the trial court is of little relevance, from the standpoint of our dissenting colleagues. They believe that we should interpret the statute to command the award of attorney fees in all cases, “unless special circumstances would render such an award unjust.”
[¶ 16] The dissent begins with an unremarkable premise: the “Legislature knew that in exercising its discretion a court would apply relevant case law and analogize to similar statutes.” From this undisputable starting point, the dissent concludes that we should borrow an interpretation of a federal statute, 42 U.S.C. § 1988, requiring that attorney fees be awarded unless special circumstances exist.
[¶ 17] The plain language of section 556 needs little help from our case law for interpretation. Further, to the extent that the statute must be interpreted, the proposed nexus between Maine’s anti-SLAPP legislation and § 1988 (designed to protect a citizen’s civil rights against state actors) is tenuous, and imposes an interpretation of a federal statute that is incongruous with this Court’s interpretation of Maine statutes.5
*1176[¶ 18] Generally, courts rely on case law when a statute is ambiguous, or silent on an issue. In this case, however, the statute is clear — attorney fees are not awarded as a matter of course, but' may be granted at the discretion of the trial court. The Legislature is familiar with the difference between the term “may” and alternatives such as “shall” or “will.” There is no reason to believe that the Legislature would have so clumsily implied a “special circumstances” standard for denying attorney fees, when in the past they have articulated it expressly. See e.g. 30-A M.R.S.A. § 4452(3)(D) (1996) (“If the municipality is the prevailing party, the municipality must be awarded reasonable attorney fees, expert witness fees and costs, unless the court finds special circumstances make the award of these fees and costs unjust”) (emphasis added). The existence of this concept, written plainly into statutory language, demonstrates the Legislature’s ability to create a presumption of attorney fees without the assistance of this Court.
[¶ 19] The dissent notes that laws are drafted against the backdrop of case law. The federal court’s interpretation of § 1988, however, does not accurately reflect our general posture towards attempts to infer attorney fees from Maine statutes. We have held:
It is well settled that Maine courts have no authority to award such fees in the absence of express statutory authorization or agreement by the parties. Because of the unique nature of attorneys’ fees, a statutory right to recover attorneys’ fees will be found only in the clearest kind of legislative language. Accordingly, a cause of action for attorneys’ fees cannot be implied from legislative intent and must be articulated in unmistakable terms.
Goodwin v. Sch. Admin. Dist. No. 35, 1998 ME 263, ¶ 13, 721 A.2d 642, 646 (citation and quotation omitted); see also Vance v. Speakman, 409 A.2d 1307, 1312 (Me.1979) (“Against the background of the firmly established common law rule denying the award of attorneys’ fees and Maine’s failure in this regard to follow the model of federal antidiscrimination laws, this court is unwilling to infer that the legislature meant such an award .... ”).
[¶ 20] These cases are not directly on point, as they interpret statutes that make no mention of attorney fees. They are emblematic, however, of the state of the common law in Maine, and our disinclination to infer attorney fees from statutory language. Just as we will not infer attorney fees in the absence of an express statutory grant, neither will we infer a presumption of attorney fees in the face of a permissive statutory grant. The grant of attorney fees in section 666 is permissive, not presumptive, and therefore the trial court did not exceed the bounds of its discretion by awarding attorney fees to Lourie or by declining to award attorney fees to' Wainwright.
The entry is:
Judgment affirmed.
Dissenting: DANA, CALKINS, and LEVY, JJ.. Maietta concedes that it removed loam from the property, however, it asserts that it did so only to prevent children from playing on mounds of it at the construction site.
. The statute provides, in part:
When a moving party asserts that the civil claims, counterclaims or cross claims against the moving party are based on the moving parly’s exercise of the moving party’s right of petition under the Constitution of the United States or the Constitution of Maine, the moving party may bring a special motion to dismiss. The court shall advance the special motion so that it may be heard and determined with as little delay as possible. The court shall grant the special motion, unless the party against whom the special motion is made shows that the moving party’s exercise of its right of petition was devoid of any reasonable factual support or any arguable basis in law and that the moving party’s acts caused actual injury to the responding party. In making its determination, the court shall consider the pleading and supporting and opposing affidavits stating the facts upon which the liability or defense is based.
14 M.R.S.A. § 556 (2003).
. The statute provides:
If the court grants a special motion to dismiss, the court may award the moving party costs and reasonable attorney's fees.
14 M.R.S.A. § 556 (emphasis added).
. The dissent notes that Wainwright and Lourie are in “almost identical positions.’’ While joined in a single complaint, however, there were two separate suits before the court. Very little of the evidence has equal probative value against both Wainwright and his attorney. Rather, most of it is applicable against one or the other. For instance, Wainwright’s public declaration that Maietta, Inc. was involved in the theft of valuable loam would have some probative value in a defamation suit against Wainwright, but would be virtually irrelevant in a defamation suit against Lourie. This is not, as the dissent suggests, a distinction without a difference. The distinction lies not in the allegations but in the evidence. Also, due to agency principles, some evidence that may have probative value against Wainwright will have no probative value with respect to Lourie, while evi*1175dence against Lourie may very well be applied against Wainwright.
. In analogizing section 556 to § 1988, the dissent cites two Maine cases, and states that "[Hollowing federal authority, we have construed ... § 1988 as meaning that a prevailing party ordinarily recovers attorney fees 'unless special circumstances would render such an award unjust.’ ” We implemented the "special circumstances” standard, however, because we were constrained to follow federal case law while interpreting a federal statute. Hence, we imposed the special circumstances test in spite of our interpretation of the statutory language, not because of it:
The text of § 1988 purports to give discretion to the trial court judge in awarding attorney fees. However, this discretion has been substantially restricted by federal courts, necessitating the judicially created "special circumstance exception,” which holds that a "prevailing party should ordinarily recover an attorney’s fee unless special circumstances would render such an award unjust.” Hensley v. Eckerhart, 461 U.S. 424, 429, 103 S.Ct. 1933, 76 L.Ed.2d 40 (1983) (emphasis added) (internal quotations omitted). Accordingly, although judicial discretion is not explicitly restricted by federal statute, we are constrained by the substantial federal jurisprudence on this point.
