Get The Facts About Involuntary Deviate Sexual Intercourse (IDSI)

A charge of involuntary deviate sexual intercourse or IDSI is a serious felony offense. If you are facing this type of charge, you are likely feeling scared about your future. It is important for you to understand this offense and to get help from an experienced Pennsylvania sex crimes attorney.

A lawyer at DiCindio Law can review the evidence in your case to determine the best defense strategies to raise in your case. Here is what you need to know about involuntary deviate sexual intercourse charges in Pennsylvania.

What is Involuntary Deviate Sexual Intercourse in Pennsylvania?

Involuntary deviate sexual intercourse is an extremely serious offense. It is codified at Pa. Stat. Ann. § 3123. Under this statute, involuntary deviate sexual intercourse is a felony of the first-degree offense. It can be committed when a defendant engages in deviate sexual intercourse in one of the following ways:

  • Using force to compel sexual intercourse
  • Threatening forcible compulsion
  • When the person is unconscious or unaware that sexual intercourse is happening
  • When the defendant administers intoxicants or substances without the knowledge of the alleged victim so that he or she is unable to consent or resist
  • When the alleged victim has a mental disability that prevents him or her from consenting
  • When the alleged victim is younger than 16 and the defendant is more than four years older, and they are not married

This is a very serious offense. However, being charged with involuntary deviate sexual intercourse is not a conviction.

The prosecutor will have the burden of proof to prove the elements of this offense beyond a reasonable doubt before you can be convicted of IDSI and sentenced. When facing this type of charge, you will need to find an aggressive and experienced sex crimes attorney who will fight to protect your freedom and rights.

Attorney Michael DiCindio has experience working as a prosecutor and as a criminal defense lawyer. He has handled criminal matters of all levels, including serious sex crimes. He is dedicated to defending his clients against serious felony offenses, including charges of involuntary deviate sexual intercourse.

Involuntary Deviate Sexual Intercourse VS. Rape

Involuntary deviate sexual intercourse has some similarities to rape but includes more types of sexual acts. Involuntary deviate sexual intercourse can include the following types of acts:

  • Penetration with objects
  • Anal sex
  • Oral sex
  • Sex acts with animals
  • Sexual intercourse with one of the previously described victims or circumstances

What Are the Penalties for a Conviction of Involuntary Deviate Sexual Intercourse?

Involuntary deviate sexual intercourse is a felony of the first degree in Pennsylvania. If you are convicted of this offense, you will face very stiff penalties. This offense carries the potential prison sentence of up to 20 years. You will also face fines of up to $25,000 and be required to register as a sex offender for the remainder of your life.

If you are required to register as a sex offender, you will have to comply with the registration and notification mandates and reveal information about yourself and where you live.

Being on the sex offender registry can cause ongoing collateral consequences such as trouble finding a job and somewhere to live. The Sexual Offender Registration and Notification Act or SORNA require sex offenders to register in every jurisdiction in which they live, go to school, and work.

If you fail to comply with the registration requirements, it is a felony offense that can result in time in prison and substantial fines.

Involuntary Deviate Sexual Intercourse with A Child

If you are facing charges of IDSI with a child, you will face even more severe penalties upon a conviction. This offense is also a felony of the first degree that is punishable by up to decades in prison.

One important thing to note is that it is not a defense to an IDSI with a child charge that you did not know the child was under the age of 13 or that he or she consented to the act.

Defending Against Involuntary Deviate Sexual Intercourse Charges

You should not take a charge of involuntary deviate sexual intercourse lightly because of the high stakes involved. You should seek a highly skilled criminal defense and sex crimes attorney. A lawyer at DiCindio Law can thoroughly investigate what occurred and evaluate the credibility of the alleged victim’s claim. Your attorney may also work closely with experts to analyze and challenge forensic evidence.

Simply facing a charge of involuntary deviate sexual intercourse does not mean that you will be found guilty or that you are guilty. You need to talk to an experienced sex offense lawyer to gain a clear understanding of your rights and the defenses that might be available to you.
