Sections 151 and 152 CPC applies only to clerical or arithmetical error, not merit-based determinations: Kerala HC
“Clerical mistakes are those that occur in the course of typing or writing, while arithmetical mistakes are those that occur during calculation. As to accidental slip or omission, the decisive test is whether it is apparent from the record that the Court intended to do something but failed to do so owing to an accidental or inadvertent omission.”
