CPC-Execution

Dear Mr. Rahaman,

you properly read order 21 of CPC for your query. By the way i think that in the execution the Decree holder must have asked for attachment of the property of Judgment Debtor, therefore you can file your objection before the executing court i.e. District Court, under order under order 21 rule 58 or any other rule as applicable to your case. you can file application for stay the execution proceedings under order 21 rule 26 read with section 151 of CPC. In the mean time you have to approach High Court for setting aside the exparte decree. 

Thanks

"Can an exparte decree of the original side of Calcutta High Court be transfered to a district court for execution? 

If the Original jurisdiction lied at the HC level due to pecuniary limits,  then subsequent execution of a decree passed by HC, doesn't the pecuniary limits and hierarchy become applicable to Executing court?
