The very purpose of granting immunity is to reach the truth.
State v. Boeglin
, 1983-NMSC-088, 100 N.M. 470, 672 P.2d 643.
Witness must testify truthfully.
— Implicit in Subsection A is the fact that a witness must testify truthfully or be subject to being prosecuted: (1) for perjury committed in such testimony or in producing such evidence; or (2) for contempt for failure to give an answer or produce evidence. To hold otherwise would make this statute meaningless.
State v. Boeglin
, 1983-NMSC-088, 100 N.M. 470, 672 P.2d 643.
Prosecutor applies for, court grants, use immunity.
— Taken together, Rule 5-116, Rule 11-412, and this section give the trial court the authority to grant use immunity when it is applied for by the prosecutor.
State v. Summerall
, 1986-NMCA-032, 105 N.M. 84, 728 P.2d 835,

Limitations to derivative use immunity.
— This statute and its implementing rules, Rule 5-116 and Rule 11-412 NMRA, allow the government to compel a witness to testify and then prosecute the witness for the crimes mentioned in the compelled testimony, as long as neither the testimony itself nor any information directly or indirectly derived from the testimony is used in the prosecution. However, it is not enough for the prosecutor to simply assert that all evidence to be used at trial was obtained prior to the defendant's immunized testimony; instead, the state should have included testimony from key witnesses, along with testimony from the prosecutor and the investigators, that the witnesses had not had access or otherwise been exposed to the defendant's immunized testimony.
