Appellant was charged, by indictment, with one count of attempted first degree sexual abuse, 1 two counts of enticing a child, 2 one count of second degree child sexual abuse, 3 and four counts of first degree child sexual abuse. 4 After a jury trial on all counts, appellant was convicted of two counts of the latter offense. On appeal he contends the trial judge committed reversible error in denying severance of the offenses and in allowing the prosecution to cross-examine defense character witnesses on the basis of a hypothetical assumption that appellant committed the acts alleged in the indictment. Appellant also asserts there were errors in sentencing. We conclude there was reversible error stemming from the first two contentions and therefore do not consider the sentencing’ questions.
I.
A.
In early June 2001, T.W. and K.K. were school aged girls (fourteen years old), who sang and aspired to be entertainers. While standing on a rail platform at a Metro station, appellant noticed them singing and introduced himself as a choreographer and dancer from New York. In a casual manner, he mentioned that he was seeking singers and dancers to go on tour. The girls stated they were singers and arranged to call appellant at a later time. K.K. called appellant that same day and made an appointment for an audition. T.W., K.K. and a male friend, who was a dancer, met appellant at the Anaeostia Metro Station. Appellant expressed some
About this time, appellant’s Mend, who had earlier talked with T.W. on the telephone, arrived. He talked to the group generally about show business and distributed his business card. When T.W. and K.K. seemed unnerved and began crying, they related their experiences in the basement to the Mend. He took them home and, later that evening, the police were called.
In the spring of 2001, another complainant, N.M., a young adult female, was introduced to appellant by the same person who had conversed with the younger complainants. At N.M.’s request she met with appellant to discuss her interest in being a choreographer. In his basement she was shown pictures of naked women, and video tapes, including pornographic material. When N.M. stated she had no interest in sexual activities, appellant danced with her and touched her in intimate ways. N.M. began to cry. Appellant masturbated in N.M.’s presence and attempted, without success, to get her to engage in oral sex. She did not report this matter to the police, but later learned that appellant had been arrested.
B.
Prior to trial appellant filed a severance motion seeking separate trials for the offenses involving the minor complainants, and those involving the adult complainant, N.M. The government opposed the motion on the ground that the evidence of the two incidents would be mutually admissible at separate trials as evidence of intent, motive, absence of mistake or accident, or to show a common scheme or plan. The government also argued that because evidence of the two incidents would be kept separate and distinct, the probative value of joining the offenses would outweigh the risk of unfair prejudice.
See Drew v. United States,
118 U.S.App. D.C. 11, 17,
Appellant did not testify at trial; however, the defense called three witnesses. One witness, a woman, testified that she was a dancer and that appellant had conducted an audition for her in his basement. She stated that appellant had demonstrated dance routines and helped to improve her skills. The remaining two witnesses were character witnesses who had known appellant for a period of years. They gave opinions regarding appellant’s truthfulness, peacefulness, honesty and good order. On cross-examination, the government, over defense counsel’s objection, asked both witnesses if they learned that “[appellant] had sexually assaulted two young girls, would that change [their] opinion”? One witness stated that his opinion of appellant would not change if such allegations were found to be true; the other testified that his opinion of appellant would change.
II.
The offenses involving the adult complainant were charged in the same indictment with the offenses involving the two ■ juvenile complainants based on the “similar character” of the offenses.
See
Super. Ct.Crim. R. 8(a). “When joinder is based on the ‘similar character’ of the offenses, a motion to sever should be granted unless (1) the evidence as to each offense is separate and distinct, and thus unlikely to be amalgamated in the jury’s mind into a single inculpatory mass, or (2) the evidence of each of the joined crimes would be admissible at the separate trial of the others.”
Arnold v. United States,
Evidence of other crimes is admissible when relevant to (1) motive, (2) intent, (3) the absence of mistake or accident, (4) a common scheme or plan embracing the commission of two or more crimes so related to each other that proof of one tends to establish the other, and (5) the identity of the person charged with the commission of the crime on trial.
118 U.SApp. D.C. 11, 16,
At the hearing on the severance question, the government narrowed its theory of mutual admissibility of the evidence to the common scheme or plan exception. It also represented that the testimony regarding the different incidents would be kept separate and distinct. As stated, the trial judge, though initially not persuaded, denied the motion and allowed the prosecution to go forward without severance. On appeal, the government again alters its position. It acknowledges that the common scheme or plan exception, applied to the circumstances of this case, is incorrect.

See Ali v. United States,
As the trial court’s decision to deny severance relied upon the theory of mutual admissibility, however, the government may not now argue on appeal that, despite the error in this reliance, the decision was proper because the evidence of each offense was separate and distinct. A discretionary decision based on an erroneous legal principle constitutes an abuse of discretion.
Hollingsworth v. United States,
III.
At trial, the prosecutor, in cross-examining the character witnesses presented by the defense, asked each witness to assume hypothetically that appellant had committed the acts alleged. Given that assumption, each witness was asked whether that hypothesis would change the opinion expressed in direct testimony. It has been a settled practice for many years that opinion or reputation evidence of a character trait may be tested by inquiring whether the witness was aware of specific acts which occurred prior to trial of the case. The purpose is to test the basis of knowledge or credibility of the particular witness.
See Michelson v. United States,
Appellant challenges this form of cross-examination, contending that the questions were flawed as an evidentiary matter and also on constitutional grounds. We agree with appellant that the questions were improper on evidentiary grounds without reaching the constitutional question.
In
Rogers, supra,
although not specifically addressing the subject of cross-examination centered on hypothetical questions, we reiterated that the reason for allowing a cross-examiner to inquire of a character witness about prior specific incidents or acts is to allow the witness to respond appropriately and to give the jury an opportunity to assess the weight of the testimony.
See Rogers, supra,
The notion that the prejudice resulting from such a guilt-assuming question necessarily outweighs its probative value is easily demonstrated by pondering the witness’s answer. The “admission” the prosecutor presumably is seeking to elicit is that the witness’s opinion of the defendant would indeed change if she were to learn that the defendant committed the crime; that is the most likely, and perhaps the only sensible, answer if the witness comprehends the question and seeks to be responsive. While this “admission” has no probative value, the prosecutor may score an unfair point by obtaining it, for the jury may think that it somehow reveals a lack of confidence in the defendant on the character witness’s part. The witness might, of course, insist that her opinion of the defendant would not change even if she were to learn that the defendant committed the crime. If the witness really understood the question and means to give such a foolish answer, we agree that it might have probative value, for it would suggest that the witness is biased in the defendant’s favor and that her opinion should be discounted. The problem, however, is that such an answer most likely indicates either that the witness is either confused by the question or not articulate, i.e., that the witness is really trying to say that she cannot believe that the defendant committed the crime as the question posits. In that most likely scenario, the answer has no legitimate probative value but is obviously prejudicial to the defendant. For these reasons, we conclude that the guilt-assuming hypothetical question posed to the character witnesses in this case was indeed objectionable because its minimal probative value was substantially outweighed by the risk of unfair prejudice to the defendant. The trial court erred in overruling the objection and permitting the question to be asked.
See Moore v. United States,
Relying upon several federal appellate decisions, appellant also asserts that the cross-examination of character witnesses by the use of guilt-assuming hypothetical questions is a violation of the Due Process Clause . primarily because it undermines the presumption of innocence.
See United States v. Oshatz,
IV.
The government asks us to affirm the convictions on the basis of harmless error. To do so, we must conclude after reviewing the weight of the evidence of guilt, as well as the nature of the errors, that the judgment of guilt was not substantially affected by the errors.
See Kotteakos, supra,
We need not decide the question of whether the severance error alone warrants reversal, however, as combined with the cross-examination error, we cannot conclude that the errors were harmless. In cases where the verdict depends on a battle between the credibility of the defendant and his accuser, “the testimony of the character witnesses ... assume[s] a position of greater importance than would be true in the ordinary case.”
