Injunctions have been made against three public representatives, including People before Profit TD Joan Collins, restraining them from organising or encouraging the blockading of Greyhound bin lorries.
Greyhound Recycling had taken the action against Ms Collins and Councillors Tina MacVeigh and Patrick Dunne, all members of People before Profit.
Lawyers for the company have also accepted an undertaking by seven named workers who are on strike, not to engage in the blockading of bin lorries or intimidating and threatening behaviour towards drivers.
Around 70 workers at the waste management company have been on strike since mid-June.
Management claim they have been joined by other protesters who have been stopping trucks and intimidating drivers.
