закреплять законодательно

[Andronik1]

подскажите пожалуйста "закреплять законодательно" есть ли какое устойчивое выражение?

контекст
...принципы должны своевременно обновляться и закрепляться соответствующими политико-правовыми актами.

[Kirsha]

These principles should be updated on a timely basis (or: in due course) and anchored in relevant (or: respective) polical and legislative acts.

может vested?

Спасибо большое! vested в этом контесте наверное не подойдет, это не много другое, а anchor, вот есть пример http://209.85.129.132/search?q=cache:9j4y0cLWew4J:www.unpcdc.org/english/focus-areas/legislative-and-regulatory-frameworks.aspx?alttemplate=&category=®ion=&country=&focus=&focusno=&selected=&focusvalue=Legislative and Regulatory Frameworks&search=&pager=20+anchored+in+relevant+legislative+acts.&cd=7&hl=en&ct=clnk&client=firefox-a
Public procurement should be anchored in a solid legislative and regulatory framework providing the principles, organisation and procedures of public procurement.

As an afterthought to my previous comment, I will go as far as to suggest another option:

These principles should be endorsed by law (or: by legislation)..

:))Yes, this is an option, but the first way of saying seems to me be more proper and natural and english-like sounding, since it is a kind of metaphor, the Brits so like to use
