A parole board was right to deny an early release to convicted former Tyco chief Dennis Kozlowski, who fleeced his company’s coffers to lavish gifts on himself — including a gold shower curtain — a New York appeals court ruled yesterday.

The state Appellate Division found that the April 2012 parole denial was “rational,” citing the board’s decision that cutting short Kozlowski’s eight- to 25-year sentence would “tend to . . . undermine respect for the law.”

The disgraced tycoon was convicted in 2005 of grand larceny and other charges. He sued last October to overturn the parole denial.
