time limit for restoration

Hi,

Its true that the petition needs to be restored within 30 days.

Limitation for filing a restoration Petition Under O 9 R 4 or O 9 R 9 C.P.C is 30 days. it can be filed even after the expiry of limitation period along with the application Under  Section 5 of Limitation Act to condone the delay in filing the restoration petition. but you are required to show a sufficient and reasonable cause to condone such delay.

There has been delay and there is sufficient cause.

Do we need to send notices again to all the repondents? Do we need repondents lawers to be present for restoration? 

Definitely the notice of your application shall be sent to the opposite party and they shall have ample opportunity to rebut your application and even court can frame a specific issue of reasons leading to delay and evidence can also be sought therein.
