About The Collateral Consequences Calculator

In 2005 New York’s Chief Judge, Judith S. Kaye, initiated the Partners in Justice program, uniting legal practitioners, educators, and judges to promote information sharing around social justice issues. Raising awareness about the collateral consequences of criminal charges served as the springboard for further discussion and action. With the guidance of a follow-up committee chaired by the Chief Judge, the Columbia University School of Law’s Lawyering in the Digital Age Clinic, headed by Profs. Conrad Johnson, Mary Zulack, and Brian Donnelly, the Law School’s Director of Educational Technology, developed the 4Cs website. The 4C’s site is a free online resource that provides high-quality content managed by experts in the major areas of New York law where collateral consequences occur. The site was created for use by judges, practitioners and academics.

The 4C’s website quickly became the most popular online resource for information about collateral consequences in New York. The Collateral Consequences Calculator was commissioned by Chief Judge Kaye and created as a companion resource to the 4C’s website. The Calculator is a joint venture between Columbia’s Lawyering in the Digital Age Clinic and the Columbia Center for New Media Teaching and Learning.

The Calculator was designed with an “at-a-glance” format so that users can quickly see where collateral consequences may occur in immigration statewide and public housing eligibility in New York City. Turnbuckles expand to reveal more information. Blue print is linked to more specific relevant information. In this way, the Calculator offers key information that will serve as a base for further research and investigation as warranted by the particular circumstances of each case, As the Calculator cannot account for the specific circumstances of each defendant, it is up to you to research and analyze the ultimate consequences of each charge in the context of the defendant’s life. You can choose how deeply to delve into a particular topic We encourage you to utilize the Calculator in conjunction with the 4C’s website and other resources to gain a fuller understanding of collateral consequences in New York.

The Calculator’s immigration content was vetted by noted immigration expert Manuel D. Vargas, founder and Senior Counsel at the Immigrant Defense Project. For additional information on the immigration consequences of criminal convictions, see resources and advisories posted at www.immigrantdefenseproject.org. The public housing eligibility content was created under the supervision of Prof. Conrad Johnson.

The CCNMTL staff who worked on this project are Anders Pearson, Zarina Mustapha, and Jessica Rowe.  We would also like to thank Frank A. Moretti, Executive Director of CCNMTL.

This calculator is not designed to provide legal advice over the Internet. Legal advice is dependent upon the specific circumstances of each situation. The information provided here is targeted toward collateral consequences in New York. The law varies from state to state, so that some information provided herein may not be correct outside New York State. In addition, immigration consequences which involve federal law may vary from one federal jurisdiction to another. While every effort is made to keep the content on this site current, the information contained herein is not guaranteed to be up-to-date. Therefore, the information provided herein cannot replace the advice of competent legal counsel licensed in your state.

Also, in the interest of making sure that defendants are aware of all possible risks, the Calculator may warn of probable or possible potential negative consequences even where there may be good arguments that conviction of a particular offense should not trigger these consequences. A skilled advocate may be able to overcome some of the potential consequences. Therefore, the information provided through the Calculator should not be taken as an absolute limitation on what such advocacy might achieve.

We welcome your feedback about the content, format and functionality of the Calculator.
