Background

  • Kathleen McGuiness, elected Delaware State Auditor in 2018, was investigated after multiple OAOA employees (whistleblowers) complained in 2020 about office spending, political activity, nepotism, and no-bid contracts.
  • DOJ investigation (2021) focused on (a) hiring/supervising McGuiness’s daughter (and benefits she received), and (b) contracts awarded to My Campaign Group/Innovate Consulting (alleged invoice "structuring").
  • DOJ executed a September 2021 search warrant for OAOA offices; encrypted digital devices required third‑party processing and a filter team to screen privileged material, delaying ESI production until shortly before trial.
  • A grand jury indicted McGuiness on five counts: Count I (Conflict of Interest) — convicted; Count II (Theft) — acquitted; Count III (Structuring/Procurement) — jury convicted but later acquitted by the trial court on legal insufficiency; Count IV (Official Misconduct) — convicted at trial and later reversed on appeal; Count V (Intimidation) — acquitted.
  • Trial (June 2022) produced mixed rulings: Superior Court denied most defense motions, sanctioned the State for late ESI by precluding it in the State’s case‑in‑chief and offered a continuance (which McGuiness declined); post‑trial the court granted judgment of acquittal on Count III, denied a new trial, and sentenced McGuiness.
  • Delaware Supreme Court: affirmed convictions in part, reversed Count IV (finding prejudicial spillover from Count III evidence), and remanded for further proceedings.

Issues

Issue McGuiness’s Argument (Plaintiff) State’s Argument (Defendant) Held
1) Brady — delayed ESI production Late ESI and lack of targeted prosecution review suppressed Brady material and prejudiced defense Delay caused by encryption/filtering; State produced ESI in searchable form promptly; continuance was offered No Brady violation; continuance was proper remedy and McGuiness declined it; no prejudice shown
2) Brady — identities/communications re: warrant affidavit Entitled to names/communications of attorneys who drafted inaccurate affidavit language to pursue selective/vindictive prosecution claims Names/communications not shown to be Brady material or relevant to selective/vindictive claims No Brady violation; information not shown likely to be exculpatory or to prejudice outcome
3) Sufficiency of evidence — Count I (Conflict of Interest) State failed to prove daughter received benefits greater than others in same class Presented comparator theories and evidence of unique cumulative benefits (hours, remote work, "banking") Affirmed: evidence sufficient that a rational jury could find statutory "personal/private interest" element met
4) Admission of Count V evidence (character/uncharged misconduct) Evidence about pre‑investigation conduct was irrelevant and unfairly prejudicial, spilled into other counts Evidence was relevant to whether McGuiness knew of investigation earlier and thus to intimidation charge Most evidence properly admitted; some 2019 evidence irrelevant but error was harmless; no new trial for this ground
5) Prejudicial spillover (Count III -> Count IV) Allowing Count III to proceed admitted highly prejudicial structuring evidence that tainted Count IV verdict Count III evidence was relevant to Count IV (Official Misconduct) and the jury was properly instructed Court applied Third Circuit Wright test, found spillover prejudicial — reversed Count IV and remanded for new trial on that count
6) Multiplicity / Double Jeopardy (Counts I and IV) Counts I and IV punish same conduct; convictions multiplicitous Statutes require different elements (Conflict of Interest requires inequitable benefit to close relative; Official Misconduct requires intent to obtain personal benefit) Rejected: Blockburger test satisfied — separate statutory elements permit separate convictions
7) Trial judge comment on witness credibility (Robinson) Judge’s in‑jury remark improperly commented on witness credibility, violating Delaware Constitution Judge was controlling examination, not weighing credibility; instruction cured any prejudice Comment was constitutional error but harmless beyond a reasonable doubt given instructions and record
8) Denial of request to appoint private counsel at State expense McGuiness argued Rule 68 / court should fund private counsel because DOJ conflicted Statute 10 Del. C. § 3925 requires seeking ODS/OCC appointment first; trial court found ODS available Denial upheld: no abuse of discretion — petitioner chose private counsel over ODS and did not show entitlement to state‑funded private counsel
