Mandatory Use of Ignition Interlock System Program

While trying to skim what's going on this legislative system I ran across HB 515 and I have to wounder what was going on:

Altering the Motor Vehicle Administration's authority to establish an Ignition Interlock System Program to require the Administration to establish the Program; requiring rather than authorizing the Administration to establish a protocol for the Program by specified regulations; providing that individuals who are convicted of, or granted probation for, specified alcohol- or drug-related driving offenses must participate in the Program; etc.

Were the courts ordering a Ignition Interlock System and MVA not following through?
