Pennsylvania law provides a potential defense to some criminal charges called collateral estoppel. Collateral estoppel may apply to bar a second trial in limited circumstances where the defendant has been acquitted of closely related charges in a first trial. The doctrine is somewhat limited in Pennsylvania because juries are not asked to provide an explanation for what they think happened; instead, jurors simply find a defendant guilty or not guilty of charges. The defense may then argue that a re-trial should be barred because a defendant has been acquitted of charges which required the same conduct with which the defendant is again charged in order for the jury to find the defendant guilty in a second trial.

The recent Pennsylvania Superior Court case of Commonwealth v. Winchester provides an example of this potential defense. In Commonwealth v. Winchester, the PA Superior Court found that the Commonwealth was not collaterally estopped from retrying a defendant for human trafficking charges after an acquittal for related robbery and theft charges because the human trafficking charges were significantly different from the related robbery and theft charges.

The Facts of Commonwealth v. Winchester

In Winchester, prosecutors alleged that the defendant contacted the complainant on backpage.com. The complainant offered sexual services through an advertisement on this website. The defendant then also contacted the complainant through text messages to set up an appointment. When the defendant arrived at the complainant’s apartment, he was let inside. The complainant was wearing a robe when she answered the door.

When the complainant went to take off her robe, the defendant pulled out a gun and pointed it at her face. The defendant then threatened her with a weapon, zip-tied her, and stole $2,700 from her. The defendant then told her that she could have her money back if she worked for him. The defendant then left her residence and told her he would return by 11:30. After he left, the complainant was able to free herself, and she called the police. The defendant then returned and was promptly arrested. When he was arrested, zip ties were found in his car matching those used to restrain the victim.

The Commonwealth filed a criminal information charging the defendant with robbery, theft by unlawful taking, terroristic threats, trafficking in individuals, and attempted involuntary servitude. At the trial, the complainant testified to the above-stated facts. The defendant also testified. He testified that he and the complainant had a prior relationship and that his communications with her, after finding her on the website, was an effort to confirm his own suspicion that the complainant was prostituting herself. The defendant testified that he called her a “whore,” which upset the complainant. This, arguably, was the reason why the complainant made up these allegations against him. The defendant denied binding her, robbing her, or telling her that he would “pimp” her out. He also testified that the zip ties in his car were related to his construction work.

Following the trial, the jury found the defendant not guilty of robbery, theft by unlawful taking, and terroristic threats. The jury did not reach a verdict on trafficking in individuals and attempted involuntary servitude. On June 5, 2017, the defendant filed a motion for dismissal, arguing that the Commonwealth intended to retry him on the charges of trafficking in individuals and attempted involuntary servitude, but the trial court should apply the doctrine of collateral estoppel and dismiss the remaining charges. A hearing was held on June 26, 2017. On August 14, 2017, the court issued an order granting the defendant’s dismissal motion. The Commonwealth then filed a timely appeal.

What is Collateral Estoppel?

The doctrine of collateral estoppel is a part of the Fifth Amendment’s guarantee against Double Jeopardy. It is important to note that the collateral estoppel clause does not automatically bar subsequent prosecution of a defendant. It only bars the re-litigation of a particular issue that has already been decided by a court. What this means is that if an issue of law, fact, or evidentiary ruling has already been decided by a prior court order, the issue cannot be re-litigated in a future lawsuit.

In Pennsylvania, courts will apply the collateral estoppel doctrine if the following threshold requirements were met: 1) the issues in the two actions are sufficiently similar and sufficiently material to justify invoking the doctrine; 2) the issue was actually litigated in the first action; and 3) a final judgment on the specific issue in question was issued in the first action. For collateral estoppel purposes, a final judgment includes any prior adjudication of an issue in another action that is sufficiently firm to be accorded conclusive effect. If the previous adjudication was based on a resolution of an issue in a manner favorable to the defendant with respect to a remaining charge, the Commonwealth is precluded from attempting to re-litigate that issue in an effort to resolve it in a contrary way at a future trial.

This sounds confusing, and it can be. To give a simple example of how collateral estoppel would prevent the Commonwealth from retrying a defendant, let’s assume that a defendant is charged with murder, aggravated assault, and simple assault. The facts of this hypothetical case are that a defendant beats a victim to death with his bare hands. Let’s further assume that after a trial, the jury is unable to reach a verdict on the murder charge, but finds the defendant not guilty of the simple assault charge. Because of the doctrine of collateral estoppel, the Commonwealth would be precluded from prosecuting the defendant on the murder charge because he was found not guilty of the simple assault charge. The reason is because the simple assault was a constituent element of the homicide charge. As such, there was already a finding that the defendant did not assault the victim and consequently the Commonwealth would be precluded from retrying the defendant on the homicide charge.

PA Superior Court Rejects Collateral Estoppel Defense Because of Differences in Statutes

Here, the Pennsylvania Superior Court overturned the trial court’s order granting the defendant’s motion to dismiss. The Superior Court concluded that the defendant’s acquittal of the robbery and theft charges did not negate the necessary elements to potentially convict him of the involuntary servitude or trafficking charges. In other words, a jury could believe that the defendant did not rob the complainant, but he did intend to force her into the sex trade. In making its decision, the Superior Court reviewed the trafficking and involuntary servitude statutes. Based on this review, the Superior Court held that the defendant’s acquittal of the robbery and theft charges did not preclude a subsequent prosecution of the trafficking and involuntary servitude offenses because robbing or stealing from her were not predicate elements of these respective charges. In other words, the defendant could have been trafficking her without robbing her or stealing from her. Therefore, the Commonwealth can retry the defendant on these remaining charges.
