GTA supplied sapphire substrates to Apple, an important ingredient of screens for smartphones but filed for protection under US regulation Chapter 11 earlier this month.
Dow Jones asked a US court to deny a request made by both Apple and GTA to keep some documents relating to their relationship under seal. It said such a move offended principles of the US constitution.
Apple had threatened GTA with a law suit for over $1 billion alleging damages.
In cases of banruptcy in the USA there are only a few conditions which would allow documents to be made unavailable to the public and Dow Jones claims no documents in this case qualified under those rules.
