As pressure mounts to revise the controversial organ transplant law, lawmakers across party lines submitted a fresh bill Friday to the Diet on top of the three bills that are already being deliberated.

The latest bill would basically prohibit those under 15 from agreeing to be an organ donor, but allow harvesting if the parents and a third party panel acknowledges brain death and agrees to the donation. The third-party panel's nod would also be required.

"It will be up to the parents to decide whether to donate their children's organs," Takumi Nemoto of the Liberal Democratic Party, the chief proponent of the new amendment, told reporters Friday.
