Review vs. appeal - when is one preferred over the other?

review can be filed when there is apperent error in the judgement or decree where the court which passed the order can correct the error. Appeals lies to higher court.

The grounds for review should be an inadvertent mistake, and it should not be like the judge has done it wantonly with full knowledge of the facts. 

New issues or points cannot be raised in review. Review is invoked only rarely particularly when there is an error apparent on the face of the record and such an error should be of patent nature, that is clearly identifiable without going very deep into the issue...

Hope i made it clear...
