(c) However, subdivision (b) does not apply to a restriction for which a power of termination has expired under this chapter if the restriction is also an equitable servitude alternatively enforceable by injunction. Such an equitable servitude shall remain enforceable by injunction and any other available remedies, but shall not be enforceable by a power of termination. This subdivision does not constitute a change in, but is declaratory of, the existing law.
However, nothing in this subdivision shall be construed to make enforceable any restriction prohibited or made unenforceable by other provisions of law, including Section 53.
