[2][3] Badalamenti was counsel of record, authored the petition for writ of certiorari, and presented oral argument in the Supreme Court of the United States for the prevailing petitioner, a fisherman, who was charged under a criminal provision, 18 U.S.C.

[4][5][6] As a child, Badalamenti lived in the Gravesend Neighborhood of Brooklyn, New York, attending Our Lady of Grace Catholic Academy.

In December 2017, Badalamenti was chosen by the bipartisan Federal Judicial Nominating Commission Middle District Conference as one of four finalists for Senators Bill Nelson and Marco Rubio to recommend to President Donald Trump to fill one of the vacancies created by Judges James D. Whittemore and John E. Steele taking senior status.

President Trump nominated Badalamenti to the seat vacated by Judge Elizabeth A. Kovachevich, who assumed senior status on December 14, 2018.

[16] In 2023, Badalamenti entered summary judgment against a plaintiff who sued the School Board of Lee County based on termination of a food supply contract with his business.

The plaintiff alleged that the termination of the contract violated his First Amendment rights because it was precipitated by a Facebook post he wrote, in which he characterized the COVID-19 pandemic as a “hoax” and denounced George Floyd.
