Some random political observations from Brazil:

The Brazilian Constitution is known for having 'constitutionalized' almost everything (like the retirement age or property ownership for foreigners). The initial text of the constitution even fixed the interest rate of the government at 12% (a stipulation that was amended during the first year of the constitution).

Brazilian parties get 'mandatory' radio and TV time that is attributed to them according to their representation in Congress. There is one hour of political programming per day distributed among the 10 to 15 parties represented in Congress.

Voting is compulsory for literate people between 18 and 70 years old, but optional for illiterate people and people between 16 and 18 as well as over 70 years of age. Illiterate people only received their right to vote in 1985. If you don't vote, you have to pay a penalty, which, in monetary terms, is actually quite low (4 BRL). But the Brazilian government keeps a recors of your voting participation. In case you ever want to work in a public domain, you need an impeccable voting record.

Like the German Fundamental Law, the Brazilian Constitution contains a so-called "perpetuity clause", which stipulates that federalism, regular elections, separation of powers and individual rights can never be abolished.
