Apple Fellow Phil Schiller testified in court on Monday that he initially opposed the 27% commission Apple now charges on purchases made outside

Apple Inc. believed there was a “significant” risk it would fail to comply with a court order to allow mobile app developers to steer customers to payment methods outside the company’s App Store when it added a new commission for those purchases,

Longtime Apple executive Phil Schiller on Monday conceded he initially opposed fees that the iPhone maker charges for in app-transactions processed outside its own payment system because he feared violating a court-ordered mandate designed to create more competition.

Schiller wasn’t sure if Apple would be allowed to charge a fee for in-app purchases made through alternative payment methods following Judge Yvonne Gonzalez Rogers’s Epic v. Apple ruling, according to the Associated Press.

Two Apple executives and three other senior Apple employees are expected to testify in California federal court next week, as a judge reconvenes a hearing into claims that the iPhone maker violated her order to allow more competition in its lucrative App Store.
