Lehmann-coached Australia will play Pakistan in the United Arab Emirates in two Tests, three ODIs and a Twenty20 International in October.
Describing the decision to ban Pakistan's most successful bowler in recent times "interesting", Lehmann said, "The ICC have obviously decided to have a crackdown on it. That's good for the game, we've got to make sure that area is right."
"If you're within the rules then fine. If you're not, then you've got to be looked at. That's what they've decided to do. What that tells coaches and players and everyone coming through the game is that you won't be able to do any of that moving forward. I think it's good for the game," Lehmann told Adelaide radio station FiveAA.
At the June meeting in Melbourne, the Cricket Committee recommended that umpires and match referees be empowered to identify and report suspect bowlers with greater confidence.
