One can read legislation and take the view that the provisions of the Act(s) do apply to one’s particular situation. Although generally this may be correct care needs to had in the knowledge that Court judgements provide interpretation  of the provisions of the Act(s) and as such a layman’s interpretation may not necessarily be correct in law.

Note that a Supreme Court judgement in one state may be used to provide an interpretation of legislation in another state if there are similarities between the legislations.

The following links are provided for guidance only and one should consider seeking legal and/or appropriate professional advice to ensure the correct interpretation is applied to your particular situation.
