It is welcome that you are resigning from the organization to pursue the higher studies. but,on the other hand it is equally important that your sudden decision of disassociation should not effect the organisation adversely.you are positively stated that you are ready to bear the cost of bond. its state your clean mind and no second thought is there.but it thoroughly depends on the organisation to relive or not considering the Business loss for the Org....considering the substituent/Replacement of yours.....considering the complexion of your work profile every thing maters.
they can't denied the reliving if all above things go smoothly.because once they issue a reliving letter to you yours legal relation of employee-employer get conclude along with all legal liabilities towards organisation.legal proceeding i don't think make any stand in the court of law because court gives decision on practical facts and not on hypothetical questions.
