"That provision envisages two ways in which the rights of a property owner may be impaired, according as the impairment is intended to deprive the owner of his rights or to restrict the exercise thereof."
The above sentence seems a tad unusual to me. I think what the author wants to say is that deprivation and restriction of property rights are two types of impairment of such rights, but I'm not sure "according as" really gets that across. It might be better to re-write the sentence, perhaps like this:
"That provision envisages two ways in which the rights of a property owner may be impaired, namely, by depriving the owner of his rights or by restricting the exercise thereof."
What do you think?
