I think we forget that there is a Supreme Power above all i.e. Allah SWT. In our life we should do good as much as possible with the aim of having Allah's kindness / blessings & leave the rest for HIM to provide protection to us. As we all know "Insaf may Barkat hai", we should as Muslim strive for it irrespective who is behind it.
Keeping the above in consideration, I think that we should go all out for the implementation of Justice system & should not negate the idea only because that it has been polticized by some political parties or the Chief Justice has become a controversial figure. Even if some political parties are trying to gain some advantage & their Neeyat is not good, we do not know from whom Allah SWT will take this work & to whom HE will punish them by putting them in their own trap.
I also do not agree with the idea that this is not the right time. We all know what our politicians are capable of achieving under the present judiciary system.
If we submit to Allah SWT & take one step in the right direction , Allah will never let us down. If we do not act now, that means we are left with same old system & same faces.
