This chapter considers several limitations upon the availability, nature, and scope of injunctive remedies available against internet intermediaries. These limitations derive from four main sources: general principles of injunctive relief, European Union law, human rights law, and specific doctrinal rules. Some are of universal application; others apply in more limited fields, such as the grant of interim injunctions, the enforcement of intellectual property rights, or to particular classes of defendants. With some exceptions, they are not specific to the internet, or even to intermediaries, and so apply in other domains and to other parties as well. This chapter divides these rules into general limitations and those specific to intellectual property. Safe harbours are addressed separately in chapter 12.
