Law vs. legislation: a typical nonnative mistake. In the US, there is a very particular distinction between the two terms. Legislation refers only to draft laws (i.e. zakonoproekty) in the works in Congress, which, if passed, become law. Thus, law and legislation are NOT interchangeable for an American. I have seen legislation occasionally used in the sense of law in some British sources and in a myriad nonnative European ones - such as Wikipedia, among others. That's all right, they simply don't know any better. So ask yourself again and again, who your intended audience is. In the absence of any such information or any specific instructions from your client, you are always better off leaving "legislation" well alone.

Igor, scrap your first option and stick to the second, which is very good (subject to the law/legislation issue discussed above). That "ratio" thing is highly confusing since there is in fact no specific ratios used for the purpose.

Не могли бы вы уточнить Спасибо, Татьяна! Не могли бы вы уточнить какой термин применить лучше law или legislation ? Для меня, технаря, это два однокалиберных понятия))
