Check again. They've overturned the physical contact part and pretended it didn't happen. Physical contact cannot be a level 1 offence. The level 2 offence was overturned and replaced with a level 1 offence to achieve a desired result. ie Rabada to play. Intention physical contact is a minimum level 2 offence under the code. This is a disgrace as I've previously stated. Your claim that it should have been a level 1 charge is incorrect under the ICC code
Philander's criticism of the decision is also a level 2 offence. There has not even been any investigation and it would be easy to verify any claims of hacking
