To what extent is there a working separation of powers (checks and balances)? From 1 to 10.

1. There is no separation of powers, neither de jure nor de facto.
2. One branch, generally the executive, has an ongoing and either informally or formally confirmed monopoly on power, which may include the colonization of other powers, even though they are institutionally differentiated.
3. The separation of powers generally is in place and functioning. Partial or temporary restrictions of checks and balances occur, but a restoration of balance is sought.
4. There is a clear separation of powers with mutual checks and balances.
