Constitution of the State of Illinois Art. I, § 9. Bail and Habeas Corpus

All persons shall be bailable by sufficient sureties, except for the following offenses where the proof is evident or the presumption great: capital offenses; offenses for which a sentence of life imprisonment may be imposed as a consequence of conviction; and felony offenses for which a sentence of imprisonment, without conditional and revocable release, shall be imposed by law as a consequence of conviction, when the court, after a hearing, determines that release of the offender would pose a real and present threat to the physical safety of any person. The privilege of the writ of habeas corpus shall not be suspended except in cases of rebellion or invasion when the public safety may require it.

Any costs accruing to a unit of local government as a result of the denial of bail pursuant to the 1986 Amendment to this Section shall be reimbursed by the State to the unit of local government.
