The case has pointed that, in order to resist to the third party, the transferee of the shares should notify or have the admission of the corporate by the certificate that verify the fixed date. If the transferor have double transferred the stock before the issue of the share certificate, is the transferor liable to the first transferee for illegality? The cases of supreme court admit that transferor is liable to the first transferee for illegality. The cases urges that the transferor of the stocks before the issue of the share certificate has the contract liability that he should give the chance to the transferee to have the entire right and profit of share.
