McFadden, Presiding Judge. This appeal concerns two rulings in a personal injury action arising from a hit-and-run accident between a vehicle driven by plaintiff Chikena L. Callaway and a vehicle owned by defendant Michael J. Quinn. The trial court granted summary judgment to Quinn on the ground that Callaway had pointed to no evidence that Quinn was driving the vehicle at the time of the accident. We find, however, that circumstantial evidence created a genuine issue of material fact as to whether Quinn was the driver, so we reverse the summary judgment. The trial court also denied Callaway’s request to add an unknown driver, alleged by Quinn, as a John Doe defendant. In so ruling, the trial court does not appear to have determined whether the claim against the John Doe defendant related back to Callaway’s original complaint, which the trial court was required to determine because the statute of limitation had expired. We therefore vacate the ruling denying Callaway’s request to add the John Doe defendant and remand the case for further proceedings not inconsistent with this opinion.1. Motion for summary judgment.Summary judgment is appropriate “if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue of material fact and that the moving party is entitled to a judgment as a matter of law.” OCGA § 9-11-56 (c). “We review a grant of summary judgment de novo, construing the evidence in the light most favorable to the nonmovant[ ] and drawing every reasonable inference in [her] favor.” Patterson v. Kevon, LLC, __ Ga. __, __ (__ SE2d __) (Case No. S17G1957, decided Aug. 20, 2018) (citation omitted). We note that the record contains some hearsay evidence, to which Quinn did not object. We may consider that evidence in reviewing the summary judgment because Quinn did not object to it in the summary judgment proceedings. See id. at __ n. 3 (considering hearsay deposition testimony in ruling that defendant was not entitled to summary judgment; although parties had reserved objections except as to the form of the question and the responsiveness of the answer during deposition, the defendant had not objected to the use of the hearsay in the subsequent summary judgment proceedings before the trial court). See also OCGA § 24-8-802 (“if a party does not properly object to hearsay, the objection shall be deemed waived, and the hearsay evidence shall be legal evidence and admissible”).So construed, the evidence showed that on May 22, 2015, Callaway was stopped in traffic when she was rear-ended by a man driving a pickup truck owned by Quinn. She was injured in the accident. The driver of the truck fled the scene, and the truck was later found, abandoned, in the parking lot of a business. A wrecker service impounded the truck.The law enforcement officer investigating the accident tried unsuccessfully to contact Quinn about it; he went to Quinn’s house, but no one would answer the door although it appeared that someone was inside. The wrecker service informed Quinn that he had to contact law enforcement to have the truck released to him, but Quinn declined to do so, and he never retrieved the truck from the wrecker service even though it contained some of his personal belongings. Based on Quinn’s behavior, the investigating officer believed that Quinn was driving the truck when it struck Callaway’s car. Quinn, however, denied driving the truck at the time of the accident. In his deposition, he testified that the truck was a “fixer-upper” that “barely ran,” which he kept parked near his house on his 3/4-acre property and only drove a few times a year. Nevertheless, Quinn maintained insurance and a current tag on the truck and kept the keys to the truck lying “on a table all the time” in the house he shared with his wife. Quinn testified that he first realized the truck was missing when he got a call from the wrecker service in June, several weeks after the accident. He never reported the truck as stolen.In his deposition, Quinn suggested that a man who stayed at his house for a few days in 2015 took the truck and crashed it into Callaway’s car. He stated that this man — who was the former boyfriend of Quinn’s wife’s sister — “disappeared” around the time of the accident. But Quinn did not know whether or not this disappearance occurred on the actual day of the accident, and he conceded that his belief that this man took the truck was mere speculation. Quinn did not know how to contact either this man or Quinn’s wife’s sister (the man’s former girlfriend). Callaway argues on appeal that the evidence, viewed in her favor, supports an inference that Quinn was the man driving the truck at the time of the accident. Quinn responds that his denial that he was driving is direct evidence rendering any conflicting circumstantial evidence nonprobative.Our Supreme Court recently discussed the rules governing circumstantial and direct evidence on summary judgment in Patterson v. Kevon, LLC, supra, __ Ga. __, explaining that [c]ircumstantial evidence can be described as evidence which does not constitute direct proof with regard to the issue of fact or the hypothesis sought to be proven by the evidence; rather, circumstantial evidence constitutes proof of other facts consistent with the hypothesis claimed. Generally, in passing upon a motion for summary judgment, a finding of fact which may be inferred but is not demanded by circumstantial evidence has no probative value against positive and uncontradicted evidence that no such fact exists. But this rule is subject to an important qualification: In neither criminal nor civil cases is it required that the proved circumstances shall show consistency with the hypothesis claimed and inconsistency with all other reasonable theories to the point of logical demonstration. Circumstantial evidence, therefore, may be sufficient for a plaintiff’s claim to survive summary judgment, if other theories are shown to be less probable. There is no requirement that other theories be conclusively excluded. . . . In those circumstances, the question as to the sufficiency of the circumstantial evidence, and its consistency or inconsistency with alternative hypotheses, is a question for the jury. And in the context of a civil jury trial, all other reasonable theories are excluded when proved circumstances of real and actual probative value cause the jury to find that the preponderance of the evidence is in favor of the hypothesis claimed, as against all other reasonable but less probable theories.
