Disgraced former state Sen. John Sampson — now behind bars for a 2015 corruption conviction — could face a second trial after an appeals court Monday reinstated two previously dismissed charges against him.

A jury in July 2015 found the Brooklyn Democrat guilty of obstruction of justice and lying to the FBI about skimming $440,000 from foreclosure deals he oversaw as a court-appointed monitor.

Sampson allegedly later took out a $188,500 loan from a pal, Edul Ahmad, to cover the shortfalls and then asked Ahmad — who eventually flipped on Sampson — to keep quiet.

Two embezzlement charges against Sampson were dropped ahead of trial because Brooklyn federal Judge Dora Irizarry determined that the statute of limitations had run out with Sampson having “completed” the alleged crimes in 1998 and 2002 while he was indicted in 2013.

On Monday, the Second Circuit Court of Appeals, overturned Irizarry, finding the 2008 withdrawal of the funds puts his alleged crimes back within the five-year statute of limitations from his 2013 indictment.

Sampson, 53, was sentenced in 2017 to five years in prison and is slated to be released in 2021.

Lawyers for Sampson declined to comment.
