Analysis: As acting PM, Olmert can make all urgent decisions
By Ze'ev Segal, Haaretz Correspondent
The Basic Law on the Government states that if the prime minister is temporarily unable to discharge his duties, the deputy prime minister will take his place. According to this constitutional law, the acting prime minister is given all the authorities of the prime minister, in every area and on every subject, so that any necessary decisions can be made. The acting prime minister is authorized to make all prime ministerial decisions, whether urgent or not.
The law does not determine the conditions under which the prime minister would be unable to fulfill his duties, but the circumstances of last night are among the most likely for this to occur.
The decision was made by the attorney general, but only after consulting with Prime Minister Ariel Sharon's physicians. The doctors will also determine when the prime minister will be able to return to his duties.
The Basic Law says that if 100 consecutive days have passed since the acting prime minister has taken on the position of the prime minister, and the prime minister has not returned to his job, the prime minister will be considered permanently unable to discharge his duties.
In such a case, on the 101st day, the government is dissolved. After consulting with the political parties represented in the Knesset, the president must appoint a Knesset member to form a new government within seven days in the above circumstance and within 14 days in the case of the prime minister's death.
