State v. Isaiah J. Knight, 309 A.3d 639

Defendant Isaiah J. Knight was charged with murder, conspiracy to commit witness tampering, and kidnapping related to the fatal shooting of Tyzier White in Newark, New Jersey.
Key witness "Zay" (Isaiah V. Knight), after identifying the defendant, was allegedly kidnapped and forced to write a recantation affidavit at the direction of defendant's relatives, who were also charged in connection with the intimidation.
The State sought to compel discovery from defense counsel of the recantation affidavit, believing it to be in defense's possession as physical evidence of witness tampering and kidnapping.
The trial court and then the Appellate Division granted the State’s motion to compel discovery; defendant appealed, citing Fifth and Sixth Amendment violations and New Jersey precedent on reciprocal discovery.
The Supreme Court of New Jersey granted leave to appeal to decide whether the discovery rules and constitutional privileges shield defense counsel from having to produce the affidavit as evidence.

Issue	State’s Argument	Knight’s Argument	Held
Whether defense must disclose affidavit as reciprocal discovery under Rule 3:13-3	Affidavit is physical evidence of a crime, subject to mandatory discovery	Only materials intended for use at trial must be disclosed	Disclosure required: Affidavit is physical evidence, not protected work product
Whether the Sixth Amendment bars compelled disclosure	Not implicated, as defense did not create/prepare affidavit; attorney-client privilege not involved	Compelled disclosure would chill defense investigations and undermine effective counsel	No Sixth Amendment violation: Affidavit not defense work product or investigation
Whether the Fifth Amendment shields from compelled disclosure	Fifth Amendment not applicable; request is to counsel, pertains to material from third parties	Compelled production is self-incriminating, as it admits to possession of evidence	No Fifth Amendment violation: Privilege is personal and not asserted for third parties
Need for search warrant vs. discovery order	Discovery rules sufficient and less intrusive than search warrants	State should use warrants, not the discovery process for such materials	Discovery order is appropriate for this context
