Indiana's IC 35-37-4.5 shields crime victims from being pressured into testing, and this guide explains the protections that keep a lie detector test from being demanded of them.
Indiana Code 35-37-4.5 prohibits law enforcement from requiring alleged sex crime victims to undergo polygraph examinations. Enacted in 2007 through P.L.41-2007, this three-section chapter ensures that a victim's refusal to take a polygraph test cannot derail an investigation, while still preserving voluntary testing rights.
TL;DR — The Short Version
- Indiana Code 35-37-4.5 prohibits law enforcement officers from requiring sex crime victims to submit to polygraph or truth-telling device examinations
- A victim's refusal to take a polygraph cannot be the sole basis for refusing to investigate, charge, or prosecute a sex offense under IC 35-42-4
- The law preserves victims' right to voluntarily submit to a polygraph if they choose to do so
- Indiana's statute was enacted in 2007 through P.L.41-2007 and aligns with federal VAWA requirements for states receiving STOP grant funding
- The statute specifically defines 'polygraph' as a device recording cardiovascular, respiratory, and galvanic skin responses — voice stress analysis tests are not covered

Indiana State Police Polygraph History

Victim Rights and Advocacy in Indiana
Sexual Assault Victims' Rights
IC 35-37-4.5 is part of a broader suite of victim protections in Indiana law. The Indiana Criminal Justice Institute (ICJI) administers victim compensation programs and has published a brochure outlining the rights of victims of sexual assault [29]Verified CJI: Victim Compensation: Rights of Victims of Sexual Assault

These rights apply whenever a victim is subject to a forensic medical examination or an interview by a law enforcement officer related to an alleged sexual assault [29]Verified CJI: Victim Compensation: Rights of Victims of Sexual Assault
Confirms Indiana sexual assault victims' rights including right to advocate, right to decline examination, and ICJI payment for forensic exam costs.
Key rights include: the right to be informed of your rights before any examination or interview; the right to speak with a victim advocate during hospital visits; the right to decline any part of a sexual assault examination; and the right to be treated with fairness, dignity, and respect throughout the criminal justice process [29]Verified CJI: Victim Compensation: Rights of Victims of Sexual Assault

Ongoing Legislative Efforts
Despite existing protections under IC 35-37-4.5, advocates continue to push for stronger safeguards. In September 2024, sexual assault survivors testified before Indiana lawmakers, urging adoption of a comprehensive survivors' bill of rights [30]Verified Sexual Assault Survivors Urge Lawmakers (Victim Testimony)
Confirms survivor testimony about being asked to submit to polygraph and broader legislative reform push in 2024. Advocate McCoy described being asked by officers to submit to a polygraph test during her case and characterized the experience as intimidating, noting the test was not ultimately used in the investigation and that polygraph results are not admissible in court regardless [7]Verified Indiana Advocate Proposes Bill of Rights for Sexual Assault Survivors
Confirms advocacy testimony about polygraph use as intimidation and push to extend protections to voice stress tests.
McCoy and other advocates have recommended that Indiana's protections extend to cover voice stress tests in addition to traditional polygraphs [7]Verified Indiana Advocate Proposes Bill of Rights for Sexual Assault Survivors

Research on Polygraph Testing in Sexual Abuse Cases
The Science Behind the Law
The legislative prohibition on mandatory victim polygraph testing is supported by a substantial body of research. A groundbreaking study published in PubMed found that in a national survey of rape crisis centres, 63 centres in 17 states reported working with survivors of sexual assault who had been polygraphed, and centres in 11 states reported that children had been polygraphed [31]Verified Revictimization by Polygraph: The Practice of Polygraphing Survivors of Sexual Assault
Confirms national survey finding 63 rape crisis centres in 17 states worked with survivors who had been polygraphed; children were polygraphed in 11 states. The researcher termed this practice "revictimization by polygraph," in which survivors are scrutinized beyond reasonable ethical practice [32]Verified Revictimization by Polygraph — ResearchGate (Extended Citations)
Confirms the term 'revictimization by polygraph' and that VAWA and the DOJ denounce polygraph use with victims.
The International Association of Chiefs of Police (IACP) has been unequivocal in its guidance, stating as a best practice recommendation to law enforcement: "Do not polygraph victims" [9]Verified LAW ENFORCEMENT – POLYGRAPH AND LIE DETECTION
Confirms VAWA STOP grant requirement, IACP best practice guidance to not polygraph victims, and scientific basis for prohibitions. The EVAWI (End Violence Against Women International) notes that the prohibitions are based on the lack of scientific evidence establishing validity for lie detection as well as the negative impact on trust, rapport, and well-being of victims [9]Verified LAW ENFORCEMENT – POLYGRAPH AND LIE DETECTION
Confirms VAWA STOP grant requirement, IACP best practice guidance to not polygraph victims, and scientific basis for prohibitions. Research shows that physiological responses associated with trauma — including elevated heart rate, irregular breathing, and sweating — closely mirror the responses associated with deception, making polygraph results especially unreliable for trauma survivors [33]Verified Utah Bans Polygraph Tests for Sexual Assault Victims (ProPublica — Half of States)
Confirms half of U.S. states have explicit prohibitions against polygraphing sexual assault victims.
Bradley, Malik, and Cullen (2011) demonstrated in their research that memory encoding processes significantly affect polygraph detection scores, with participants who incidentally encoded crime details showing significantly lower detection rates [34]Verified Memory Instructions, Vocalization, Mock Crimes, and Concealed Information Tests with a Polygraph
Demonstrates how memory encoding processes significantly affect polygraph detection scores with implications for trauma victims. This has important implications for trauma victims whose memories may be fragmented or encoded differently due to the stress response.
The Value of Polygraph in Offender-Focused Applications
While research cautions against polygraphing victims, the evidence strongly supports the value of polygraph testing in offender-focused applications. The Ahlmeyer et al. (2000) landmark study demonstrated substantial increases in reported victim counts and offense variety when polygraph was incorporated into sex offender treatment, showing that the polygraph serves as a powerful truth-facilitating tool for accountability purposes [24]Verified The Impact of Polygraphy on Admissions of Victims and Offenses in Adult Sexual Offenders
Landmark study showing polygraph testing dramatically increased admissions of previously undisclosed victims and offenses in sex offender treatment.
Soshnikov (2008) established comprehensive procedural standards for forensic polygraph practice, detailing three primary testing methodologies and 16 specific investigative applications [35]Verified Полиграф в практике расследования преступлений (The Polygraph in Practice in the Investigation of Crimes)
Establishes comprehensive procedural standards for forensic polygraph practice with 16 specific investigative applications. Pollina et al. (2004) found that while laboratory and field examinees showed differences in response magnitudes, classification accuracy did not significantly differ between settings, supporting the generalizability of polygraph research to real-world criminal investigations [36]Verified A Comparison of Polygraph Data Obtained from Individuals Involved in Mock Crimes and Actual Criminal Investigations
Confirms classification accuracy did not significantly differ between laboratory and field settings, supporting generalizability of polygraph research. Hikita (1969) demonstrated field validity through Probing Peak of Tension tests, with 77.56% of examinees displaying physiological reactions confirmed by confessions Verified Results of Probing Peak of Tension Tests Used in Other Crimes and Its Relation to the Suspected Conditions
Demonstrates 77.56% of examinees showed physiological reactions confirmed by confessions in field polygraph testing.
These findings reinforce the distinction that IC 35-37-4.5 makes: polygraph technology is a valuable investigative and treatment tool for law enforcement and corrections, but should not be used coercively against victims of sexual violence.
