State v. Forsythe, 390 P.3d 931

Background

In Nov. 2013 Joseph Forsythe allegedly brutally assaulted his wife Giana (PFMA). While jailed under a no-contact order he sent multiple letters to her, some instructing her to lie about her injuries and refuse to testify.
Giana gave the letters to prosecutors; Forsythe was charged with felony tampering with a witness and misdemeanor PFMA in District Court; State sought persistent felony offender designation.
Forsythe moved in limine, arguing the letters were confidential spousal communications protected by § 26-1-802, MCA; the State argued the letters were intimidating/subornation and thus unprivileged.
At a pretrial hearing Deputy Brad Tucker (law enforcement) testified comparing handwriting samples; defense objected that Tucker had not been disclosed as an expert. The court admitted the letters and later allowed them into evidence; Giana was permitted only to confirm receipt, not contents, under an initial privilege ruling.
Jury convicted Forsythe of tampering and PFMA; district court imposed prison terms and a $20 information technology surcharge. Forsythe appealed evidentiary rulings and the surcharge.

Issues

Issue	Plaintiff's Argument (Forsythe)	Defendant's Argument (State)	Held
Whether letters were protected by spousal privilege	Letters were confidential marital communications protected by § 26‑1‑802, MCA; no threats so privilege applies	Letters were threatening/suborned perjury and thus fall within common‑law exception; also tampering charge is a crime against spouse so statutory exception applies	Court: Letters not privileged — content was intimidating/suborning perjury and tampering arose from same proceeding as PFMA; privilege exception applies
Whether lay witness (Tucker) could give handwriting/authentication testimony without being disclosed as expert	Tucker’s handwriting comparison exceeded lay scope and Rule 901(b)(2) because he had no prior non‑case familiarity; admission was improper	State conceded notice error but argued testimony was harmless because other evidence authenticated letters	Court: Admission of Tucker’s expert opinion without expert designation was error, but error was trial (non‑structural) error and harmless in light of cumulative/authenticating evidence; conviction stands
Whether admission of Tucker’s testimony was prejudicial requiring reversal	Testimony was technical expert opinion crucial to proving tampering (that all letters were by same author); absence of rebuttal/expert notice prejudiced defense	State points to other admissible evidence (Giana’s receipt, other handwriting exemplars, signature specimens) showing no reasonable possibility tainted testimony contributed	Concurring dissent would reverse; majority finds no reasonable possibility of contribution and deems error harmless
Whether district court illegally imposed $20 information technology surcharge	N/A (defendant seeks correction)	State concedes statute authorizes single $10 surcharge per case	Court: $20 surcharge illegal; amends judgment to reduce to $10 per statute under appellate modification authority
