Sharon sues Cady for defamation. Sharon claimed that Cady had written in a diary that Sharon is a "sad, old, drug pusher." The diary was later photocopied and distributed at Sharon's workplace. Cady denied that she had written the statement.

The matter goes to trial and both sides request a jury.

At trial, one of the key questions was whether Cady had, in fact, written the statement. Hoping to prove that it was Cady, Sharon's attorney plans to call Gretchen as a witness. Gretchen is a handwriting expert who will testify that Cady had done the writing.

Regina, the trial judge, rules that Gretchen does not meet the appropriate qualifications to be an expert witness. As a result, Gretchen is not allowed to testify. Judge Regina tells the jury to decide whether Cady wrote the statement based on their own evaluation of Cady's handwriting.

The jury eventually determined that Cady is not liable. Sharon wants to appeal.

On what basis may she appeal?
