What is a Cahill Disposition in a 2nd Offense Massachusetts OUI Charge?

If you were charged with a second offense Massachusetts OUI charge, you may be eligible for a disposition of your case known as a Cahill disposition.

What is a Cahill Disposition?

The term Cahill disposition derives from the case of Commonwealth v. Cahill, 442 Mass. 127 (2004) which held that the Registry of Motor Vehicles must honor the decision of the court to treat a second offense OUI as a 1st offense if it occurs more than 10 years from the date of the 1st drunk driving conviction.

This means if you are charged with a second offense OUI, but the court gives you the 24D program, and imposes all of the penalties applicable to a 1st offense OUI charge, including the 45 day loss of license and assignment of the 24D program, the Massachusetts Registry of Motor Vehicles must honor that disposition. The Registry of Motor Vehicles, under the Cahill decision, will allow you to obtain your license back, provided that you have the ignition interlock installed in your vehicle and you will be required to maintain the ignition interlock device for a period of the three years.

Am I Eligible for a Cahill Disposition?

If you were charged with a second offense OUI and your 1st offense was more than 10 years ago, it is up to the Court as to whether or not they will treat it as a 1st offense OUI.

You are INELIGIBLE if:
You are ineligible for a Cahill disposition if you receive the 14 day in-patient as part of the resolution of the case OR if you have more than one prior OUI offense that is over ten years old.

What are the Potential Penalties?

A second offense Massachusetts OUI charge, where your 1st offense is more than 10 years from your second offense charge will allow you to get your license back, provided that you have the ignition interlock installed in your vehicle.

Attorney DelSignore discusses the penalties of a second OUI charge and the Cahill Disposition

If the court does not treat your second offense OUI as a 1st offense, even though more than 10 years have passed between the two offenses, you will not be eligible for the Cahill disposition.In other words, if the district court judge imposes the 14 day in-patient program, as part of a plea or after trial, the Registry of Motor Vehicles will not be obligated to allow you to reinstate your license within 45 days, with the ignition interlock requirement.

It will instead impose the second offense license suspension penalties, a 2 year license loss with the ignition interlock requirement. If the court approves the Cahill disposition, you will be eligible to get your hardship license on the three year breathalyzer refusal suspension should you refuse a breathalyzer test. The ignition interlock device must be maintained in your vehicle for a period of the hardship, plus an additional 2 years. The ignition interlock device will require you to pay a monthly monitoring fee and an installation fee. The Massachusetts Registry of Motor Vehicles does criminalize any attempts to tamper with or destroy the ignition interlock device. If you took a breath test and receive the Cahill disposition, you will have to leave the ignition interlock in your car for three years.


This was the second time in just over three years I had been arrested for OUI. I felt comfortable and confident in hiring Michael as he explained he was familiar with the court my case was in and had an understanding of the judges after trying many cases there. During trial, Mike made an excellent effort in cross-examining and ultimately de-bunking many of the officers claims. Going into court that day, I thought for sure I was going to lose my driver's license for at least 60 days and more likely for 2 years. Thanks to Mikes expertise, I ended up with a not guilty finding on the DUI and a simple 1 year probation and $900 in total court fees.

I will recommend him to anyone I know that wants to fight a DUI charge. Thanks again to Mike and his staff at DelSignore Law!

Client Reviews
Michael was very professional and explained the process clearly and told us to be patient. After one year the charges got dismissed in the trial. Excellent knowledge of the court systems in the area of Boston. Would highly recommend him Ashwani
A careless decision on my part left me facing charges which would have severely hampered my ability to stay employed and support myself. But attorney DelSignore's skillful analysis and challenging of the evidence against me resulted in a conviction on a lesser charge. Now I'll be able to go on with my life, having learned a lesson I'll never forget. Thank you, Michael. Scott
Mike stuck with my case for 3.5 years and always kept me informed regarding the status. Ultimately, because of his due diligence, we ended up with an OUI not guilty verdict. This case could have gone many ways but his thorough review of the case and exceptional preparedness for trial ultimately drove a positive outcome. Thank you Mike! David
Michael DelSignore did an amazing job with my case! He was always available to answer any questions I had and helped walked me through the entire process. I could not have done it without them! I highly recommend choosing this law firm to deal with your legal needs, you will not be dissatisfied. Ashley
I cannot express the gratitude towards Michael for his amazing work and help. It was a very stressful event and they certainly put me at as much ease as possible. From start to finish it took 14 months and all the way through they were both very engaged with me. Today was worth the wait, Michael was great in court and I was rightfully found not guilty. I would recommend Michael over and over again. Claire
