Dennis P. Derrick is a seasoned attorney with an established appellate practice in Massachusetts since 1977. He is a duly licensed attorney in good standing and authorized to practice law in Massachusetts.

He is a Member of the Bar of the United States Supreme Court, the State courts of Massachusetts and Connecticut and the federal courts of the First Circuit Court of Appeals, the Second Circuit Court of Appeals and the federal district courts for the Districts of Massachusetts and Connecticut.

Besides preparing petitions for certiorari and amicus curiae Briefs for submission to the U.S. Supreme Court, Mr. Derrick has authored the prevailing Brief in over 345 appeals in both state and federal court, including 79 reversals of the lower court’s judgment. Many of these decisions implicate important statements of the substantive law and have addressed emerging issues in family law, constitutional law, civil rights, land use regulation, federal practice and procedure, tort law and commercial law. These decisions are identified in Mr. Derrick’s Appellate Track Record below.

Of the sixty-plus petitions Mr. Derrick has authored, two provided immediate relief for petitioners. See Blaisdell v. City of Rochester, 544 U.S. 957 (2005), granting the petition and remanding the case to the court of appeals; Boyd v. Wisdom, Dkt. No. 05-603 (2/16/06), where on the strength of the petition, a settlement favorable to the petitioner was reached prior to the Court’s vote. In six other petitions (Information Systems v. United States, Dkt. No. 06-234; Goldblatt v. Ebert, Dkt. No. 07-1097; UFO Chuting of Hawaii v. Smith, Dkt. No. 07-1427; Pinnick v. Corboy & Demetrio, PC,  Dkt. No. 08-1129; Harmon v. Pollock, Dkt. No. 09-1195; and Onwuteaka v. Serna, Dkt. No. 15-511), the Court ordered respondents to answer Mr. Derrick’s  arguments, an event which increases ninefold the likelihood of a petition’s grant. One of these petitions (Onwuteaka v. Serna, supra) was chosen by SCOTUSblog.com as its “Petition of the Day” on 12/27/2015 and a “Petition to Watch” on February 19, 2016.

Mr. Derrick graduated from Christian Brothers Academy in Syracuse, New York, and received his bachelor's degree from George Washington University in Washington, D.C. He is an honors graduate of Suffolk University Law School in Boston. While in law school, he served as Note Editor of the Law Review and authored several Notes and Case Comments for that journal as well as inaugurating independent student newspapers at the law school.

After serving as law clerk for United States District Judge Robert C. Zampano in New Haven, Connecticut, Mr. Derrick entered private practice in New Haven and then Boston, representing plaintiffs in civil litigation and defendants in medical malpractice actions. Since 1977, he has concentrated his practice in the prosecution of civil and criminal appeals in both the State and federal courts in the Commonwealth of Massachusetts as well as the preparation of petitions for certiorari and amicus curiae Briefs in the United States Supreme Court.

Mr. Derrick’s son (Geoffrey J. Derrick, Esq.) and daughter-in-law (Lauren M. Weinstein, Esq.), both lawyers and erstwhile law clerks for federal judges, practice law in Washington, D.C.

Highlights of Mr. Derrick's Supreme Court practice:

-representing the petitioner and authoring the prevailing petition for certiorari in Blaisdell v. City of Rochester, 544 U.S. 957(2005), where the United States Supreme Court GRANTED the petition, VACATED the judgment below and REMANDED the case to the First Circuit Court of Appeals on the issue of whether the doctrine of federal jurisdiction expressed in Rooker v.  Fidelity Trust Co., 263 U.S. 413(1923) and District of Columbia Court of Appeals v. Feldman, 460 U.S. 462(1983), was wrongly applied in order to deprive the petitioner of a trial on his civil rights claims in federal court;

–representing the petitioner in Boyd v. Roy Wisdom et al., U.S. Supreme Court No. 05-603, where the petitioner was punished with substantial financial sanctions and referred for disciplinary proceedings for bringing a fair housing claim in federal district court.
