oh me too in my trial i did four issues but it depends on the question, if it specifically asks for issues, eg. "with reference to legal issues faced by family members, discuss remedies and the difficulties in gaining access to these remedies" so ofcourse for a question like that you incorporate as many issues as you could
but for the question i'm doing now, "evaluate the effectiveness of the legal system in responding to changing community values in terms of achieving justice for family members." there is so much to say on how childrens rights have changed that i am only doing that and recognition of same-sex relationships, because under those headings are many more issues...
plus the criteria says:
apply criteria to evaluate the effectiveness of the legal system or to assess the place of the law
demonstrate an understanding of relevant legal information and issues
ilustrate your answer with examples of legislation...
present a sustaind...
so it does say issues on there, which could be two, on yours it said several issues, so you would want to do a minimum three, i guess thats why they stress to read the rubric
