Thesis titleAn examination of the efficacy of regulatory licensing regimes as a means of guaranteeing effective animal welfare protection in the UK

Animal welfare licensing regimes generally follow a process whereby an individual must be deemed to comply with a particular set of animal welfare regulations in order
to be granted, and retain, a licence to keep or use animals in a particular manner.

The set of regulations will differ dependent on the specific use that the licensee intends to put the animals to. This research will consider the efficacy of the common
regulatory model of the licensing regime as a means of guaranteeing animal welfare protection in law in the United Kingdom.

The research aims to address the gap in available information on the practical application of four pieces of legislation, whose provisions are delivered by way of licensing, to regulate four different practices involving animals.

The legislation to be considered is:
1. The Dangerous Wild Animals Act 1974 or The Pet Animals Act 1951
2. The Zoo Licensing Act 1981
3. The Wild Animals in Travelling Circus Regulations 2012 (Implementation date January 2013)
