Madison Teachers, Inc. v. Walker, 2014 WI 99, 358 Wis. 2d 1, 851 N.W.2d 337, 12-2067. This section does not violate the Contract Clause, article I, section 12, of the Wisconsin Constitution. Nothing in 2011 Wis. Act 10 purports to reduce, impair, or affect in any way benefits that have already accrued to plan members. This section modifies only the method by which the Milwaukee ERS is funded; the pension, disability, and death benefits that accrue to plan members pursuant to the terms and conditions in the Milwaukee Retirement System ordinance remain unaffected.
