dissenting.
I respectfully dissent.
I wholly support the majority’s urging that decisions in child custody cases be rendered promptly. Perhaps they ought even to be given a priority over others, all along the judicial path. There is, e.g., a statutory time mandate for decisions on motions. OCGA § 15-6-21. Even where no change in custody is ultimately ordered, the child suffers because of the effect which limbo has on the relationship among the family members and towards the child. Where a change of custody is finally ordered, the delay usually means the child has been subjected to more of the selfsame harm causing the change, during the interim created solely by the slow wheels. Thus the judicial process itself contributes to the ongoing harm to the child. This all can be exacerbated by temporarily switching custody back and forth via supersedeas grants and denials. OCGA §§ 15-11-64; 5-6-35 (h).
Here, unless the father temporarily took custody between the trial court’s denial of the mother’s request for supersedeas and our grant of supersedeas (a period of twenty-one days), and assuming the father did not take custody immediately upon receipt of the trial court’s appealed-from order of March 12, 1986, the child has been in the custody deemed not in his best interest, for nearly three years from the filing of the petition setting forth the grounds. He is now age eight and was then about five.
The final result is that the change of custody of the child will be effected some three years after the mother’s alleged cohabitation with a man not her husband, which cohabitation is the ground for the or*759dered change. If that environment has continued, the judicial system has been complicitous in the further harm to the child.
I also agree that there is no authority to reverse the judgment of the trial court on the ground of the delay per se. The Uniform Juvenile Court Rules make no such time requirements. 254 Ga. 757, as amended, 255 Ga. 739. The closest legal basis may be OCGA § 19-9-21 (a) (4), (7), and (b), but it does not constitute authority for the proposition. Nor had the mother filed a motion to which OCGA § 15-6-21 would have applied, or sought the awkward and cumbersome mandamus. Graham v. Cavender, 252 Ga. 123 (311 SE2d 832) (1984). Although the state constitution declares that one of its purposes is to “promote the interest and happiness ... of the family” and requires “uniform court rules . . . which shall provide for the speedy, efficient, and inexpensive resolution of disputes and prosecutions,” it imposes time constraints only on the appellate courts. Ga. Const. 1983, Preamble; Art. VI, Sec. IX, Pars. I and II.
Where, then, do I dissent? In the conclusion that the evidence was sufficient to authorize a change of custody.
The law is that “[o]nce a permanent award of child custody has been made, when the non-custodial parent seeks to change custody, the trial court must determine whether there has been a material change of conditions affecting the welfare of the child. [Cit.]” Gibson v. Pierce, 176 Ga. App. 287 (335 SE2d 658) (1985). The opinion in Robinson v. Ashmore, 232 Ga. 498, 501-502 (II) (207 SE2d 484) (1974) speaks of the necessity of showing a “material effect” on the interest and welfare of the child and quotes from Handley v. Handley, 204 Ga. 57, 59 (48 SE2d 827) (1948), which describes it more fully as change “which might substantially affect the health, happiness, or welfare of the children.” It is emphasized repeatedly in the cases that “any consideration of custody must always be made in the light of the best interests of the child involved . . . primary consideration [must be given] to the welfare of the child.” See OCGA § 19-9-3.
In the instant case the court found that the mother’s home was suitable “except for the fact that the mother is cohabiting with a man to whom she is not married while the child is living with her,” and on that basis found a material change of conditions adversely affecting the welfare of the child. True, it found changes in the father’s conditions to be favorable. But that itself would not be a valid ground on which to change custody.
I assume for the purpose of this dissent that the alleged cohabitation negatively affected the child’s welfare, as did the trial court, although that poses another legal problem. The court must make a finding that the change in circumstances “had in fact had a material adverse effect on the child,” not only that there has been a change of conditions. Evans v. Stowe, 181 Ga. App. 489, 491 (4) (352 SE2d 811) *760(1987); see Howard v. Fincher, 161 Ga. App. 411, 413 (288 SE2d 338) (1982).
Decided June 16, 1987 Rehearing denied July 21, 1987 Arline S. Kerman, W. Edward Meeks, for appellant. Carl A. Veline, Jr., for appellee.The evidence that the mother “is cohabiting” (when? at the time of the hearing in May 1985 or at the time of the decision in March 1986 or at the time the petition was filed in August 1984, or at any of these times and continuing as in Bell v. Bell, 154 Ga. App. 290 (267 SE2d 894) (1980)) is less than scanty. The transcript, which is now in the record although it was not when the trial court made its decision, shows that the evidence is purely speculative.
The only evidence that appellant and one Ethridge dwelled or lived together as husband and wife was not legally cognizable. The father said the child said Ethridge had lived with them at a previous apartment but conceded that the child’s statement could not be taken for the truth of it. The mother and Ethridge and Ethridge’s daughter steadfastly denied it. The father’s counsel conceded that his private investigator’s testimony should be discounted. The resident manager and the neighbor offered no evidence of cohabitation, just their con-clusory lay opinions, although the neighbor heard what she believed to be lovemaking once. Such evidence is an insufficient foundation for a finding of fact. City of Atlanta v. Hightower, 177 Ga. App. 140, 143 (338 SE2d 683) (1985); Bankers Health &c. Ins. Co. v. Fryhofer, 114 Ga. App. 107, 110 (1) (150 SE2d 365) (1966).
“ ‘Though the trial judge is given a discretion, he is restricted to the evidence and unauthorized to change the custody where there is no evidence to show new and material conditions that affect the welfare of the child. (Cit.)’ [Cit.]” Evans, supra at 491.
I would for this reason reverse.
