We have received from the Georgia Court of Appeals the following certified questions:
“This case involves the grant of summary judgment based upon expert opinion testimony, as well as the record on appeal to the superior court from a probate court after which a motion for summary judgment was filed and granted.
“1. Does the rule as expressed in such cases as
Howard v. Walker,
“2. Does the rule apply to all situations where expert opinion is used in summary judgment cases?
“3. Please advise whether or not the rule in
Ginn v. Morgan,
“4. Where in a summary judgment proceeding evidence is presented to prove an issue which may be based upon non-expert opinion testimony and/or expert opinion testimony, in the event expert opinion testimony is used, then in that event, will the opposing *746 party in summary judgment be required to produce expert opinion testimony to controvert said expert opinion testimony, or may non-expert opinion testimony be used to controvert expert opinion testimony?”
Most of these questions may be resolved by reference to our opinion in Howard v. Walker, supra:
“The seminal case in Georgia regarding opinion evidence in summary judgment cases was
Ginn v. Morgan,
“In the case now before us, in order for the plaintiff to recover he must produce opinion testimony of an expert witness.
Berman v. Rubin,
“Although not required to do so at trial, the defendant here has produced an expert’s opinion in support of his motion for summary judgment. The plaintiff, although required at a minimum to produce a contrary expert opinion at trial in order to prevail, produced no contrary opinion in opposition to the motion for summary judgment. In a case such as this there is no genuine issue to be resolved by a jury.
“We hold that in those cases where the plaintiff must produce an expert’s opinion in order to prevail at trial, when the defendant produces an expert’s opinion in his favor on motion for summary judgment and the plaintiff fails to produce a contrary expert opinion in opposition to that motion, then there is no genuine issue to be tried by the jury and it is not error to grant summary jüdgment to the defendant.
Anderson v. Crippen,
“Ginn v. Morgan,
supra, and its progeny continue to be correct insofar as nonexpert opinion cases are concerned and insofar as motions for summary judgment in favor of plaintiffs are concerned.”
Howard v. Walker,
supra,
The principles enunciated in Howard are applied consistently in *747 Parker v. Knight, supra, and Payne v. Golden, supra.
Hence, the answer to Question One will depend upon whether or not a contention of fact is capable of proof
only
by expert testimony which, of course, would include medical and legal malpractice cases.
Shea v. Phillips,
Because the value of real property may be established both by expert opinion evidence and otherwise, matters relative to the establishing of such value are without the rule, and are governed by the principles of
Harrison v. Tuggle,
supra,
Harrison
fails to address the requirement that a plaintiff may not establish a variance from the standard of care in medical or legal malpractice cases without expert opinion testimony from which the jury could determine malpractice. This latter requirement is properly a
prerequisite
for the submission of a case to the jury. (Note the narrow exception in the second division of
Shea v. Phillips,
supra,
Accordingly, Question Two is answered in the negative.
Question Three is answered as follows: Ginn v. Morgan, supra, and Harrison v. Tuggle, supra, have been modified by Howard v. Walker, supra, only to the extent discussed in our address to Question One.
Question Four is answered in the affirmative only as to those instances wherein a plaintiff is required to establish an essential element of his case by expert opinion testimony, and in the negative as to all other instances. 1
Certified questions answered as stated in the above opinion.
