Qualified?

Hi what is "qualified" in this context?

"The recognized legitimate role for competing interests in Canadian society is qualified by the view that the majority will prevail when a compromise solution cannot be found. Also, according to the principle of majority rule, any political decision can be changed once the majority has altered its own position. A belief in parliamentary democracy also suggests support for political equality, eg, support for the notion of "one person, one vote." The last feature of parliamentary democracies, popular sovereignty, is expressed in regular elections and the involvement of citizens in the political process."
