v.
GENERAL MOTORS CORPORATION, Henry Clifton Baldwin, Individually, and Linda Hayworth Hyatt, Individually.
No. COA00-155.
Court of Appeals of North Carolina.
February 20, 2001.
*318 Twiggs, Abrams, Strickland & Trehy, by Douglas B. Abrams, Raleigh, for plaintiff-appellant.
Teague, Rotenstreich & Stanaland, by Stephen G. Teague, Greensboro, for defendant-appellee Hyatt.
Burton & Sue, by Walter K. Burton and James D. Secor, III, Greensboro, for unnamed defendant-appellee Allstate.
THOMAS, Judge.
Plaintiff appeals from a jury verdict of $6,000.00 in a personal injury action and sets forth six assignments of error. For reasons discussed herein, we hold the trial court committed no error.
The facts surrounding the car accident are not in dispute. Plaintiff was driving south on Randleman Road in Guilford County when the rear of his vehicle was struck by a vehicle operated by defendant Henry Baldwin. Baldwin's vehicle was then struck by a vehicle driven by defendant Linda Hyatt. Plaintiff brought suit against both Baldwin and Hyatt alleging multiple injuries. Initially, Hyatt denied liability in her answer to plaintiff's complaint while unnamed defendant Allstate (the underinsured motorist insurer) admitted liability. Just before trial began, plaintiff reached a settlement with Baldwin. Allstate then amended its answer to deny negligence and Hyatt amended her answer to allege contributory negligence against plaintiff. The case went to trial during the week of 26 April 1999 and the jury returned a verdict for plaintiff in the amount of $6,000.00. Plaintiff filed a motion for a new trial, which was denied. Plaintiff filed notice of appeal on 24 June 1999.
By plaintiff's first assignment of error, he argues the trial court erred in permitting Allstate to participate in the trial when it earlier had said it would not participate in the pre-trial conference or trial. We disagree.
By statute, a UIM insurer has the right to participate in a trial without being named if application is made and approved by the presiding trial judge. N.C. Gen.Stat. § 20-279.21(b)(4) (1999). Allstate's counsel filed a notice of appearance on 27 April 1999, which the court recognized in an order in limine filed on 28 April 1999. Plaintiff argues the North Carolina Rules of Civil Procedure preclude a party from participating in a trial if that party elects not to participate in the pre-trial conference. N.C. Rules of Civ.Proc., Rule 16 (1999). However, there is no evidence Allstate failed to participate in the pre-trial conference. There is evidence the pre-trial conference actually occurred after Walter Burton appeared before the court as counsel for Allstate. Thus, this assignment of error is rejected.
By plaintiff's second and third assignments of error, he argues the trial court committed reversible error in allowing Allstate and Hyatt to amend their answers on the first day of trial. We disagree.
*319 A motion to amend pleadings is addressed to the sound discretion of the trial court; the trial court's ruling is not reviewable absent a showing of an abuse of discretion. Haas v. Kelso, 76 N.C.App. 77, 80, 331 S.E.2d 759, 761 (1985); see also N.C. Gen.Stat. § 1A-1, Rule 15 (1999). "An abuse of discretion occurs when the trial court's ruling `is so arbitrary that it could not have been the result of a reasoned decision.'" Chicora Country Club, Inc. v. Town of Erwin, 128 N.C.App. 101, 109, 493 S.E.2d 797, 802 (1997), disc. review denied, 347 N.C. 670, 500 S.E.2d 84 (1998) (quoting White v. White, 312 N.C. 770, 777, 324 S.E.2d 829, 833 (1985)). No abuse of discretion has been shown.
Additionally, reversible error occurs when the defendant shows that but for the error a different result would have been reached. N.C. Gen.Stat. § 15A-1443(a) (1999). The jury found for plaintiff on those issues. By prevailing, even if there were error, and we conclude there was not, it was not prejudicial and is rendered moot.
By plaintiff's fourth assignment of error, he argues the trial court erred in refusing to permit plaintiff to offer Allstate's original answer as evidence in the case. We disagree.
The trial court denied plaintiff's motion in limine, which sought to offer both the original and amended answers into evidence. A motion in limine seeks pretrial determination of the admissibility of evidence proposed to be introduced at trial; its determination will not be reversed absent a showing of an abuse of the trial court's discretion. Nunnery v. Baucom, 135 N.C.App. 556, 521 S.E.2d 479 (1999). The trial judge found the probative value of the answers was substantially outweighed by the danger of prejudice and confusion of the issues by the jury, pursuant to Rule 403 of the N.C. Rules of Evidence. Moreover, in negligence cases, it is not generally permissible to introduce evidence of liability insurance or to make any reference of its existence in the presence of the jury. Carolina Timber Management Co. v. Bell, 21 N.C.App. 143, 203 S.E.2d 339, cert. denied, 285 N.C. 376, 205 S.E.2d 97 (1974). As with assignments of error three and four, plaintiff prevailed on those issues at trial. Thus, there is no prejudicial error.
By plaintiff's fifth assignment of error, he argues the trial court erred in refusing to permit plaintiff to offer evidence of loss of services to himself. We disagree.
Plaintiff attempted to use an economist as his expert witness to show the value of the plaintiff's loss of his own services. An expert witness is qualified to testify if "scientific, technical or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue[.]" N.C. Gen.Stat. § 8C-1, Rule 702(a) (1999); State v. Jones, 337 N.C. 198, 209, 446 S.E.2d 32, 39 (1994). The trial court correctly concluded the jury was capable of rendering a decision on the value of a person's services to himself because such is a matter of common knowledge. No abuse of the trial court's discretion has been shown and, accordingly, we find no error.
By plaintiff's sixth and final assignment of error, he argues the trial court erred in refusing to grant a new trial because the jury award was improperly low. We disagree.
The relevant statute provides that a new trial may be granted due to "[e]xcessive or inadequate damages appearing to have been given under the influence of passion or prejudice[.]" N.C. Gen.Stat. § 1A-1, Rule 59(a)(6) (1999). "A motion for a new trial on the grounds of inadequate damages is addressed to the sound discretion of the trial court[.]" Estate of Smith v. Underwood, 127 N.C.App. 1, 12, 487 S.E.2d 807, 814, disc. review denied, 347 N.C. 398, 494 S.E.2d 410 (1997) (quoting Pelzer v. United Parcel Service, 126 N.C.App. 305, 484 S.E.2d 849, 853, disc. review denied, 346 N.C. 549, 488 S.E.2d 808 (1997)). The plaintiff relies on Robertson v. Stanley, 285 N.C. 561, 206 S.E.2d 190 (1974), which held that uncontroverted damages cannot be arbitrarily ignored by the jury. However, in the instant case, plaintiff's damages were contested by defendants Hyatt and Allstate. Plaintiff's own witness, Dr. Arthur Carter, testified that many of plaintiff's injuries did not result from the accident at issue. Plaintiff has not shown an *320 abuse of the trial court's discretion; thus the assignment of error is rejected.
For the reasons stated herein, we find no error.
NO ERROR.
MARTIN and TIMMONS-GOODSON, JJ., concur.
