Attorney-witness rule

The Attorney-witness rule prohibits a lawyer from serving as both advocate and witness in the same proceeding. In Rusty Sabich’s murder trial, the rule became a tactical fault line: Tommy Molto was listed as a potential prosecution witness even as Nico Delia Guardia intended to have him help try the case. Sandy Stern’s challenge forced the prosecution to choose between Molto’s participation as counsel and the use of his account of Sabich’s response to an accusation of murder.

The rule and its conflict in the case

Sandy Stern identified a practical problem in the prosecution’s witness list. If Molto was expected to testify, he could not also act as one of the trial lawyers. Stern therefore proposed a motion to disqualify him. The motion was not only about courtroom roles: it could also prevent the prosecution from using Sabich’s statement to Molto, which the defense considered potentially damaging if introduced or used in cross-examination.

For the defense, the issue offered a way to unsettle the prosecution before trial. Stern reasoned that Molto would be vulnerable as a witness because of his close professional and political association with Delia Guardia, but that the statement could still be useful to the prosecution against Sabich. The motion put that strategic tension into procedural form: the prosecution could not simply preserve every advantage while disregarding the incompatibility between witness and advocate.

Lyttle’s ruling and the prosecution’s choice

With three weeks remaining before trial, Delia Guardia argued that removing one of the prosecutors would impose an onerous burden and might leave the state unable to proceed on schedule. Larren Lyttle rejected the idea that the trial’s importance or publicity justified an exception. He treated the prohibition on a lawyer acting as both witness and advocate as an established courtroom rule and questioned how the prosecution had expected to proceed with Molto on its witness list.

Lyttle also addressed the statement at issue: Molto’s account that Sabich had answered an accusation of murder affirmatively. The judge’s intervention made the prosecution’s options plain. It could lose Molto as an advocate and pursue the testimony, or keep him on the trial team and abandon that proof. Delia Guardia chose to retain Molto. Sabich’s statement to him consequently disappeared from the prosecution’s case.

When Molto tried to address the matter himself, Lyttle stopped him from arguing about the admissibility of his own testimony. The exchange gave the rule an immediate, concrete force: Molto could not resolve the conflict by advocating for the evidence whose use depended on his own witness role.

Procedural boundary and significance

The episode shows how a procedural rule can shape a case without deciding the underlying question of guilt. The attorney-witness prohibition did not establish what Sabich had meant or whether the prosecution’s broader allegations were true. It limited how the prosecution could present one piece of evidence and required Delia Guardia to surrender either Molto’s role as trial counsel or the value of Molto’s testimony.

The dispute also distinguishes this issue from the trial’s later battles over physical evidence. Those disputes concerned whether evidence could be admitted despite defects in its handling; the attorney-witness conflict concerned whether the same lawyer could occupy two incompatible roles in one proceeding. Its consequence was narrower but direct: the prosecution proceeded with Molto as an advocate and without his account of Sabich’s remark.
