The Supreme Court [of Ohio] has held that: the qualification or competency of a witness to testify as an expert or to give his opinion on a particular subject rests with the trial court, and, on appeal, its rulings with respect to such matters will ordinarily not be reversed unless there is a clear showing that the court abused its discretion." Midwest Materials, Inc. v. Aetna Freight Lines, Inc., 11th Dist. Lake No. 9-021, 1982 WL 5659, at *1 (Sept. 24, 1982), citing Ohio Turnpike Commission v. Ellis, 164 Ohio St. 377 (1955). {ΒΆ34} As noted earlier, "an abuse of discretion is the trial court's 'failure to exercise sound, reasonable, and legal decision-making.'"
Tiner v. State, supra. The fact that a defendant who has knowingly and intelligently pleaded guilty later becomes dissatisfied with the sentence he received does not, alone, constitute a ground for invalidating the guilty plea. Chapman v. State, 412 So.2d 1276 (Ala.Crim.App. 1982)."
