Mr Huang’s representatives may have been counting on a higher turnout to achieve a significant protest vote, rather than an outright block; were the Bain trio to be removed, it would have triggered an immediate penalty of $352m. Gome’s board, for its part, has simply reinstated the directors, as is its right.---taken from Here
I think of "as" as one of the trickiest words in English. Now I have trouble with the bold part.
1 Can I use "which" to substitute for "as" without changing the meaning?
2 Can I read "as is its right" as a relative clause modifying the main clause?
May I have your opinions? Thanks in advance.
