What happen to our judiciary system?

It's look like there are two (2) judiciary system in Malaysia, one for ruling coalition and one more for opposition. If the case was brought by ruling coalition, most of the case will be quickly heard and processed but sadly to say, if the case was oppositions', they need to wait and wait... These thing can be clearly seen in the case of Perak state ruling....  IMHO, every case no matter who brought it, since that case was our nation's interest should be judge earlier.... sad to live in Malaysia if this case still cannot be solved.
In Linggam case, how can our judiciary system can let them go? the truth is already there but........
