(65 ILCS 55/15) (from Ch. 24, par. 808.15)
    Sec. 15. The judgments of the court shall be final as to all the issues involved, and the proceedings in the cause shall be subject to review by appeal as in other civil cases: Provided, however, that by mutual consent the same may be vacated or modified notwithstanding the expiration of 30 days from the rendition of such judgment, except as provided in this Act.
    Such judgments shall have the effect of several judgments as to each tract or parcel of land assessed, and no appeal from any such judgment shall invalidate or delay the judgments, except as to the property concerning which the appeal is taken.
    Such judgment shall be liens on behalf of the municipality making the improvement, for the payment of which the special tax or special assessment is levied, on the property assessed from the date thereof, to the same extent and of equal force and validity as a lien for the general taxes until such judgments are paid or the property against which any such judgment is entered is sold to pay the same.
    The municipality on behalf of which such lien is created may sell and assign the same and either the municipality or the assignees of such judgment lien may at any time in its or his own name, file a complaint to foreclose the lien in the same manner that foreclosures are by law permitted in case of delinquent general taxes: Provided, however, that no forfeiture of the property sought to be foreclosed shall have been had as a prerequisite to such foreclosure.
