What is the meaning of disposed

It means case disposed in accordance of Law. 

To find out if it was rejected or what was the petition's outcome, one needs to review 'certified copy' of Final Order of the concerned Court. 

The meaning of disposed off means the case has been closed.  It may be allowed or dismissed. You have to check it up in net or section of the court or after obtaining certified copy.  Usually this word will be used in High courts and Supreme courts. 

The case before the court has been concluded by an order or judgment is called as disposed.
