functus officio ?
Please correct me if I am wrong ...
I believed about meaning of 'functus officio' that .....................
................ "unless the litigant climbs the doorsteps of the upper court to seek the redressal against adverse verdict and to same court " ..........
and ................ "unless ... thus the jurisdiction of court which passed order/decree/judgment etc happens to be seized by upper court, by allowing to admit/file the redressal prayer vide revision/appeal etc etc)" ................
and ................ "unless the jurisdiction of trial court is not extinct/ not ceased to exist by limitation period of "review" or ................ unless the condonation of delay is not rejected" ................
and ................ "unless the litigant hasn't taken recourse to 'review' or "inherent jurisdiction" to redress the adverse verdict at the same court!!! (and needless to say that prayer shouldn't apparantly look like an "appeal in disguise" etc ) ................
then and then only ................ the trial court becomes "functus officio" in regards to 'trial' otherwise not.
Review /inherent jurisdiction .... Courts don't just have powers to pass erroneous judgments/decrees/orders ....... and Courts can't just say ... "I don't have powers to withdraw my own decision although erroneous one!! .... but please go to upper court!!" ...... but also does have powers to set aside its own verdict .......... if it fits in the definitions and limited scope to do that!!!
Here whether you call the erroneous verdict or "error on the face of record" in the trial (and hence the erroneous judgment!! ) .... it is a different view from a different window ......... to same scenario!!!! ......................
Else victim of adverse and erroneous verdict would be made to run from pillars to post to set it nullified .............
....... and may also have to face the other ordeals of 'staying the execution' of the impugned order etc etc.
