1. Yes: denotes two different situations:
    a) an existence of a legally protected and enforceable right; (typical formulations)
    b) In some cases the individual category cannot be taken as denoting a right. For example, categories on citizenship, on criminal law provisions, on obligatory primary education do not entail any rights in traditional sense. In such cases the symbol "yes" denotes the existence of some legal framework which only offers some legal guarantees short of enforceable rights.

2. No: denotes absence of certain constitutional right or certain legal provisions (see 1b).

3. Principle (P): is used to describe a state's obligation to strive towards achieving a certain goal and not a right enforceable by an individual. (typical formulations)

4. "!" (Note): this sign is used to highlight that a provision in some way departs from the typical formulation set forth in the index of categories. It can signify that:
    a. the formulation of a specific constitutional provision is atypical i.e. that it departs from the definition of the category in the index of categories,
    b. the constitutional provision contains some material limitations
If, for example, the constitution abolishes death penalty but allows its use when it is established by military penal law in times of war (e.g. Art. 15/1 of the Spanish Constitution), we have indicated this exception by using "!".
    c. the constitutional provision is limited to a certain class of persons
A constitution can guarantee special protection to new mothers only and not to mothers in general (Art. 54/1 of the Albanian Constitution).
    d. if a constitutional provision affords higher protection than outlined in the index of categories.
This would be the case if the constitution guarantees the right to citizenship (Art. 26/1 of the Portuguese Constitution)
    e. if this symbol appears next to "No" then it denotes that although the constitution does not include a certain right it does contain some information on the right in question that might be useful.
If the constitutional provision, for example, only states that a right will be regulated by law (Art. 72 of the Turkish Constitution).
