LSP License Resignation Record - James J. Decoulos
Summary
In February 2019, the Massachusetts Board of Registration of Hazardous Waste Site Cleanup Professionals issued a Final Order imposing a one-year suspension of the Licensed Site Professional (LSP) license of James J. Decoulos, arising from a complaint filed by a client in 2005 who refused to pay his bill. The decision was challenged at the administrative level and the Massachusetts courts, ultimately concluding with the U.S. Supreme Court, which denied review on October 7, 2025 (No. 24-1312).
Resignation
The suspension took effect on February 21, 2025, while appeals continued. On November 17, 2025, after the Supreme Court declined review, Decoulos resigned from LSP practice and permanently relinquished License No. 9360. Rather than return to LSP practice when the suspension ended, he chose to leave the program permanently. His resignation was not an admission of the Board’s findings.
Why the Case was Contested
The matter took more than 13 years to resolve. During that time Decoulos was denied subpoenas for witnesses he considered essential, and relevant evidence was sealed. The courts upheld the Board’s decision. While Decoulos respects that outcome as final, he continues to believe the proceeding did not afford him the due process guaranteed by the Massachusetts and United States Constitutions.
