Former NSW policeman Roger Rogerson.
The 64-year-old pleaded guilty in Downing Centre District Court to one count of giving false evidence to the PIC in May, 1999.
Judge Peter Berman today sentenced Rogerson to two and a half years in jail, saying he had deliberately lied to a commission whose objective was to uncover and weed out corruption.
"This was not some spur of the moment decision which he immediately regretted," Judge Berman said.
Rogerson faced a maximum five years' jail for the offence but Judge Berman took into account his guilty plea, age, evidence of good character, and the mental hardship he would suffer in custody.
Judge Berman ordered Rogerson to serve at least one year of the sentence.
He will be eligible for parole on February 17, 2006.
Last October, Judge Berman sentenced Rogerson's wife, Anne Melocco, to two years' periodic detention for the same offence.
They were charged after lying to a PIC hearing into alleged corruption at Liverpool City Council in Sydney's south west.
