In federal cases, investigators often try to leverage the cooperation of defendants to further their investigations or build stronger cases against others.

When it benefits their objectives, federal officials may offer options to defendants that could lead to more favorable outcomes in exchange for valuable information.

One common option is a proffer letter, also known as a “Queen for a Day” agreement. This process allows defendants to participate in a session where they can share information that might assist the prosecution. Under the terms of the proffer agreement, the information disclosed during this session generally cannot be used directly against the defendant in later proceedings, giving them a degree of protection while cooperating.

While this might sound like an enticing offer, it’s important to approach this arrangement with extreme caution. It carries potential risks and implications.

Let’s explore how proffer agreements work and how you and your attorney can determine whether this strategy might help you achieve a more favorable outcome in your case.

What is a ‘Queen for a Day’ agreement?

A “Queen for a Day” agreement, formally known as a proffer or proffer letter, is a legal arrangement that allows a defendant, witness, or person of interest to share information about a crime with federal investigators. This agreement offers some protection, as prosecutors generally agree not to use the information disclosed during the proffer session against the individual in court.

However, the protection is conditional. If the individual provides false, misleading, or incomplete information, prosecutors may nullify the agreement, and any potential plea deal could be withdrawn. For this reason, accuracy and transparency during a proffer session are critical.

A “Queen for a Day” agreement can also be a strategic tool in negotiating a plea deal. By offering valuable and credible information, a defendant can demonstrate their cooperation and potentially secure a reduced sentence or other favorable terms for their role in the case. This strategy allows defendants to actively shape the outcome of their case while assisting investigators in building a stronger prosecution.

Because of the complexities and potential risks involved, consulting with an experienced attorney is essential before entering into a proffer agreement. A lawyer can help assess whether this strategy is appropriate and ensure your rights are fully protected throughout the process.

What is the purpose of a proffer letter or agreement?

The purpose of a proffer letter or agreement is multifaceted and serves both the prosecution and the defendant in various ways.

First, it provides an opportunity for the prosecution to gather information about criminal activity that could strengthen their investigation or build a stronger case.

Second, it allows defendants to negotiate for leniency, such as a reduced sentence or a more favorable plea deal, in exchange for their valuable cooperation.

Lastly, proffer sessions enable the prosecution to evaluate the defendant’s information to determine whether it is valuable, honest, and credible before deciding how to proceed.

How does a proffer agreement work?

The proffer agreement process may vary case-by-case, but it usually follows the following basic format. 

  1. Negotiation and signing the agreement – Before any conversation, you and your attorney will review and sign the proffer agreement. This document outlines the terms of your cooperation and the limitations of the protections offered. In this agreement, the prosecution agrees to not use the information given at the proffer session against the defendant.
  2. Proffer session – You will have a meeting with the prosecution, which may include investigators. At this session the defendant will provide detailed information about the crime, case or your part in it. It is important to show the prosecution the value that you add to their case, as a witness or participant.
  3. Evaluation by prosecutors – Prosecutors will assess the information you have given them and whether it is credible and beneficial. At this point, they will decide what kind of plea bargain or leniency they want to offer you and whether they want to collaborate with you. 

Important things to keep in mind when considering a proffer agreement

  • Honesty is crucial – The defendant has to be 100% truthful at the proffer session. Any agreement can be jeopardized with any false or misleading information and can potentially harm the defendant’s case. This includes the defendant trying to minimize their role in the crime. 
  • The agreement is not a promise – At the point of the agreement, there is no guarantee that the prosecution will want to collaborate with the defendant. This means it’s possible there will be no plea bargain.  
  • It is not risk free – While prosecutors cannot use your proffer statements against the defendant, they may share the information with investigators and can use it for impeachment purposes if you end up being a witness or offering testimony contrary to your proffer statement. 
  • Attorney-client privilege – The attorney-client privilege will of course still apply during this process. However, statements to the prosecutor can be shared with other law enforcement agencies.
  • Strategic decision – The decision to enter into a “Queen for a Day” agreement is a significant strategic decision. You will need to discuss this with your defense attorney, who should consider the potential risks and benefits.
