prevailing of HC SC bail orders on lower courts....

Further more.......................

Is it any exception under constitutional law???

It depends upon judge to judge to follow the verdict of upper court in respect of other accused persons in the same case. Bail is a matter of discretion of court so it cannot be forced as precedient. Supreme court has clarified this point various times and judge cannot be restrained to follow his line of action in bail matters.

Is there any law really?? Or it is only hearsay???

there is no law for providing bail to co-accused when the higher court has granted bail to other.

Granting bail is discretion of the court ........ If High Court has granted bail to a co-accused it does not mean that the Sessions courts are bound by law to grant bail to a another co-accused ........ further it could depend on the mindset of the judge .... the role of the accused ..... progress of investigation ........ the past of the co-accused .... whether there are chances of him hampering the investigation and/or tampering with the evidence ..... etc ....... based on all these the grant of bail to such a co-accused would be considered .......

Court see the role of accused in the matter (Charge Sheet), see evidence and thereafter decided for bail.

This dirscretion power has become a toy for the courts??...... hon. judges perhaps don't know that the undertrial is passing his days in great agony and pain. I even doubt that my advocate friends have any knowlege about a single day in any indian jail. My friends ...its not jail but hell  on the earth. They say it's a judicial custody ...but i doubt if any of our hon judges have spent a single minute there to see or hear the agony of people (under trial) in any indian jail. I can write pages on this but dont want to because as indians we do injustice and are taught to accept injustice. Unless we are a business tycoon, a politician or a police dept head.(retired bhi chalta hai e.g. rathod). My point is that  the hon. lower courts should use their power and release the undertrial as precidents. There are lacs of pending cases in india,  after sixty years of independence we dont want to leave what the britishers leftover for us?. Jootha khane ki aadat pad gai hai? But,...who will bell the cat?? Here you blow the wistle and you yourself are out. I pity the system. God save us from all this. Especially the U.T's family.
