RTA BUDGET-LINE ITEM VETO

Amends the Metropolitan Transit Authority Act and the Regional Transportation Authority Act. Requires that the budget and 2-year financial plan submitted by each Service Board (Chicago Transit Authority, Suburban Bus Board, and Commuter Rail Board) to the Regional Transportation Authority to include specific line-items for revenues and expenses and be divided into detailed categories established by rule by the Board of the Regional Transportation Authority. Provides that the Board of the Regional Transportation Authority may reduce or veto any item of appropriations in the budget or plan submitted by a Service Board and shall return the item vetoed or reduced with its objections to the Service Board that submitted the budget or plan. Makes similar changes in provisions concerning the approval of a Service Board's revised budget.
