People v. Carter

Wharton's Rule ordinarily prevents a conspiracy prosecution when the substantive offense necessarily requires the participation of two persons. Its focus is on the legal nature and elements of the target offense, not on whether multiple participants happened to be useful or necessary in the particular case.

Carter improperly treated aiding and abetting as the target offense. Michigan's aiding-and-abetting statute is not a separate substantive crime; it is a means of making one who procures, counsels, aids, or abets a completed offense punishable as a principal. The relevant target offense was therefore extortion itself.

Extortion requires a malicious threat and an intent to obtain money or another pecuniary advantage. It does not require an agreement or the participation of more than one person. Thus, the conspiracy involved a danger beyond that necessarily present in every extortion.

The aiding-and-abetting statute also directs that an aider be prosecuted and punished as if he directly committed the substantive offense. Allowing a principal to face both conspiracy and extortion charges while immunizing an aider from the conspiracy charge would conflict with that equal-treatment command.

Under Blockburger, offenses are different if each requires proof of a fact the other does not. Conspiracy requires an agreement to commit a crime, while aiding and abetting requires active assistance or participation in a completed crime committed by a principal.

Michigan conspiracy is complete when the unlawful agreement is formed; it requires no overt act and does not depend on the success of the planned crime. By contrast, accessory liability requires a completed substantive offense and conduct that procures, counsels, aids, or abets that offense.

Neither crime is necessarily included in the other. A person can assist in a completed crime without having previously agreed to commit it, and a person can join an unlawful agreement without doing the additional act needed to aid or abet the completed crime.

That some trial evidence supported both charges did not make the offenses the same for federal double-jeopardy purposes. The federal analysis turns on the legal elements, not on overlap in the evidence introduced at trial.

Michigan's double-jeopardy analysis considers the facts proved at trial as well as the offenses' elements. It can bar multiple punishment for cognate offenses when the proof of one offense necessarily proves the other and the offenses share a sufficiently close relationship in purpose and protected societal interest.

The two offenses did not share the required common class, category, or statutory purpose. The conspiracy statute punishes criminal planning and the special dangers of group criminal activity, whereas the aiding-and-abetting statute punishes participation in the actual commission of the substantive crime.

The jury's finding that Carter aided and abetted extortion did not necessarily establish an agreement, which is the indispensable element of conspiracy. Evidence that Carter drafted the note, met Kimble after the crime, and divided the proceeds supported active participation, but required a separate inference to prove a prior agreement.

Likewise, proof of conspiracy did not necessarily prove aiding and abetting. An agreement alone does not establish the completed crime or the active assistance required for accessory liability. The jury could also have found that Carter and Kimble reached an agreement during their afternoon meeting on December 18 and that Carter later performed the separate acts supporting aider-and-abettor liability.

The prosecution had a duty to endorse and produce res gestae witnesses, generally understood as witnesses to an event within the criminal transaction whose testimony helps disclose the circumstances of the charged offense. Morris was not present for the extortion, had never seen Carter near the time of the crime, and was too remote from the criminal event to qualify.

Morris had seen Kimble, apparently alone, watching the Consumers Power building on several occasions before the robbery. But that account did not necessarily contradict Kimble's testimony that Carter participated in planning or surveillance; Carter could have been outside Morris's view, and Kimble's earlier presence near the building did not negate Carter's later involvement.

Carter's general request for exculpatory material triggered the Agurs materiality standard. Under that standard, nondisclosure requires reversal only if the omitted evidence would create a reasonable doubt that did not otherwise exist.

Morris's testimony would not have created that doubt in light of the direct, corroborated evidence against Carter. Kimble and Potter described Carter's planning and participation, and the victim's prior friendship with Carter and his knowledge of her family corroborated his connection to the threatening note.

Potter testified somewhat equivocally that the detective said he had a particular suspect in mind and confirmed that she selected the right photograph. The detective did not recall making those remarks. Even accepting Potter's account, the detective did not identify which photograph was his suspect before she selected Carter's image.

The record showed that Potter viewed approximately 200 photographs over several sessions and identified Carter from the final group. Questions about whether she viewed the entire group and errors in parts of her description went principally to her credibility, rather than demonstrating that the procedure itself was improperly suggestive.

The Kachar factors supplied an independent basis for her courtroom identification. Potter had seen Carter at least six times before the offense, including at the Sewell Hotel and Leake's Lounge, and she accurately described distinctive features such as his prominent eyes and flared nostrils despite mistakenly describing him as clean-shaven.

Her prior familiarity with Carter occurred in ordinary circumstances rather than under the stress of being a crime victim. Her eventual identification of his photograph was clear and unequivocal, supporting the admission of her in-court identification.

After Carter introduced prison employment records to challenge Kimble's account that the two met at prison, the prosecutor elicited on cross-examination that Carter had been dismissed for assaulting a supervisor. Evidence of unrelated misconduct is generally inadmissible when offered merely to suggest that a defendant is a bad person.

The trial judge immediately instructed the jurors not to consider Carter's suspension or dismissal in deciding whether he committed the charged offenses. The court told them expressly that using the evidence for that purpose would be error.

The instruction was prompt, no further objection followed it, and the subject was not substantially pursued. Carter later testified that he had been reinstated with back pay after an investigation. Under these circumstances, the cautionary instruction cured any prejudice from the disputed testimony.
