The new bylaws have introduced a concept of "in good standing". Every member organization is by default in good standing, but they may loose it by being overdue on paying their member dues (or for certain violations of their Member agreements, if the agreements so specify). Eventually, if the situation is not resolved, members who lost good standing might lose their membership altogether, but for at least for a while, they can stay, while in bad standing.

In the bylaws, losing good standing cause the member to lose their right to vote in board elections and other decisions taken by consortium members (such as board recalls, amending bylaws, etc…). Otherwise, their general ability to participate in W3C is unaffected.

From a Process point of view, should members who have lost good standing lose any right?
I would suggest that they can generally continue to participate normally, but lose the right to vote in AB and TAG elections, to take part in AC-Reviews, and to initiate or vote in AC-Appeals.
