The National Assembly is formed on three occasions: when a new president takes the oath of office; when an indictment against the President of the Republic is brought to the State Tribunal (Trybunał Stanu); and when a president's permanent incapacity to exercise his duties due to the state of his health is declared.
A Asemblea Nacional reúnese en tres ocasións: cando o novo presidente xura o cargo; cando se presenta unha imputación ao presidente no Tribunal do Estado (Trybunał Stanu); e cando se declara a incapacidade do presidente para exercer os seus deberes por motivos de saúde.
