2-19     exclusive authority:
2-20                 (1)  to enforce this subchapter in any area of this

2-26           SECTION 3.  This Act takes effect September 1, 1999.
 3-1           SECTION 4.  The importance of this legislation and the
 3-2     crowded condition of the calendars in both houses create an
 3-3     emergency and an imperative public necessity that the
 3-4     constitutional rule requiring bills to be read on three several
 3-5     days in each house be suspended, and this rule is hereby suspended.
