Book excerpt: This Model Animal Welfare Act has been designed to serve as a basic template and guidance document for those interested in enacting new legislation or improving existing animal protection legislation. It has been drafted using an extensive comparative law exercise, taking into account 'best practice' in the field. Thus it is aspirational in nature; seeking to provide the best possible structures, systems and provisions to protect the welfare of animals. This may mean that countries which are just starting to establish animal welfare requirements might decide to introduce its provisions progressively. In such cases, a strategic approach (step-wise and prioritised) is recommended. This could also be considered in cases where countries already have structures, systems and provisions that have been introduced gradually over time, but remain less than optimal. The important principle is that each country works progressively towards the best possible protection for the welfare of its animal population, and indeed - as elaborated in the Three Rs approach - the eventual reduction and replacement of any uses of animals which compromise their welfare.The purpose of this Model Animal Welfare Act is to function as an 'umbrella' or 'framework' law. It represents an international unification and harmonisation of animal protection and welfare legislation, which can be adapted or modified - if the circumstances require - in Common Law as well as Civil Law systems. Elements of both legal orders have been considered and incorporated to achieve (as far as possible for the present day) a comprehensive, far-reaching and progressive approach to animal welfare legislation which takes account of the desired expedience when it comes to prevention of animal cruelty and abuse, establishing responsibility and the principle of care towards the animal, promoting the education and sensitisation of the population, as well as offering effective solutions for efficient law enforcement. This Model Act was created in order to govern people's behaviour, while other civil or religious legal systems may take a very different form (for example, be limited to 'codes' or 'edicts'). Nonetheless, elements of this Act can also be used for inspiration in creating, amending or interpreting these.
