The ruling upheld a controversial state law that allowed a lobbyist for the Illinois Federation of Teachers, David Piccioli, to become certified as a substitute teacher in December 2006 by working one day at a Springfield elementary school — and to buy pension credit for his 10 previous years working as a lobbyist. That sweet deal qualified him for a pension windfall from a teachers retirement fund that as of late 2018 carried an unfunded liability of more than $75 billion-with-a-B. Because he also draws a pension from a previous job as a House Democratic aide, Piccioli’s total pension income now rises to nearly $100,000. His pensionable income from the Teachers’ Retirement System is based off his salary from the IFT— another questionable pension loophole, which the Supreme Court upheld last year.
