And it had also ended a"controlling shareholder protocol",which since 2018 has allowed Crown executives to share confidential information directly with Mr Packer,who owns 36 per cent of Crown but has not had any official position with the company since he left its board in 2018.
Both agreements have been examined in recent weeks during at-times explosive hearings of the ongoing NSW Independent Liquor and Gaming Authority inquiry into Crown,which is considering whether it should keep the licence to its soon-to-open Sydney casino.

The inquiry raised the suggestion of insider trading relating to Crown sending confidential financial forecasts to Mr Packer and CPH executives under the agreements early last year,at a time when they were negotiating to sell a 19.9 per cent stake in Crown for $1.7 billion.
The CPH executives shared the confidential company profit forecasts with the buyer of the shares,Hong Kong group Melco Resorts,the inquiry heard.
However CPH and Crown executives have argued the confidential financial forecasts were not"price sensitive"because they were broadly in line with market expectations.
