Robert Jenkins, a member of the Snellville City Council, sued Joe Anderson alleging that Anderson made various defamatory statements about him in numerous letters and e-mails sent to several individuals. Anderson filed a motion to dismiss the defamation claims asserting that the statements constituted free speech about public matters that was protected by Georgia’s anti-SLAPP Strategic Lawsuits Against Public Participation statute, OCGA § 9-11-11.1. Jenkins appeals from the trial court’s order granting the motion to dismiss. For the following reasons, we affirm in part and reverse in part. 1. Georgia’s anti-SLAPP statute declares it to be in the public interest to encourage citizens to participate in matters of public significance by exercising the constitutional rights to free speech and to petition the government for redress of grievances, and to ensure that those rights are not chilled through abuse of the judicial process. OCGA § 9-11-11.1 a; Atlanta Humane Society v. Harkins , 278 Ga. 451, 452 603 SE2d 289 2004. When the judicial process is used to assert a claim against a person or entity arising from an act which could reasonably be construed as in furtherance of those constitutional rights, OCGA § 9-11-11.1 b requires that a written verification accompany the claim which certifies: that the party and his or her attorney of record, if any, have read the claim; that to the best of their knowledge, information, and belief formed after reasonable inquiry it is well grounded in fact and is warranted by existing law or a good faith argument for the extension, modification, or reversal of existing law; that the act forming the basis for the claim is not a privileged communication under paragraph 4 of Code Section 51-5-7; and that the claim is not interposed for any improper purpose such as to suppress a person’s or entity’s right of free speech or right to petition government, or to harass, or to cause unnecessary delay or needless increase in the cost of litigation. If the trial court makes a substantive, evidentiary determination that the verification is false because the claim infringes on the rights of free speech or petition as defined by the statute, then the court may dismiss the claim. OCGA § 9-11-11.1 b; Harkins , 278 Ga. at 454.
After a hearing, the trial court made a substantive, evidentiary determination that the verification filed in this case was partially false because the statements Anderson made about Jenkins in a letter to the Snellville City Manager were privileged pursuant to OCGA § 51-5-7 4.1 We are unable to address Jenkins’s claim that this determination was erroneous because the alleged statements in the letter are not part of the record on appeal. Although the record shows that the trial court considered the letter at the hearing, neither the letter nor the substance of the statements in the letter was included in the record transmitted to this Court, and Jenkins’s appellate brief provides no record citation for the statements. Jenkins has the burden of showing affirmatively by the record that the trial court erroneously found that the statements in the letter were privileged pursuant to OCGA § 51-5-7 4, and he cannot carry this burden on a record that does not contain the statements. Walker v. Board of Regents &c. , 254 Ga. App. 15, 18 561 SE2d 178 2002. “In the absence of a sufficient record, we must assume that the trial court’s ruling was proper.” Steele v. Atlanta Maternal-Fetal Medicine, P.C. , 283 Ga. App. 274, 277 641 SE2d 257 2007 punctuation and citation omitted. Accordingly, we affirm the trial court’s order to the extent it dismissed Jenkins’s claim that Anderson defamed him in the letter to the Snellville City Manager.
