Martial law
When in martial law, the military gained all powers of the state, including to dissolve the parliament and suspend the constitution as it did in its fifth announcement. Under martial law, the only legal framework within the Egyptian territory was the numbered announcements from the military. These announcements could for instance order any civilian laws to come back into force. The military announcements (communiqués) were the de facto only constitution and legal framework for the Egyptian territory. It meant that all affairs of the state were bound by the Geneva Conventions.
Under the current president Abdel Fattah el-Sisi, a series of constitutional amendments passed in 2019 granted the military authority to intervene in national politics to "preserve the constitution and democracy, protect the basic principles of the state and its civil nature, and protect the people's rights and freedoms". The armed forces were separately granted policing responsibilities to arrest civilians and "protect public and vital facilities".

Finland: The Preparedness Act (SDK 1552/2011, Finnish: valmiuslaki) is a law in Finnish legislation, enacted in accordance with the constitutional procedure. The purpose of the Act is to give the authorities sufficient powers in times of war and other exceptional circumstances. During a state of defence (war), there is also the Defence Status Act, the provisions of which override the Preparedness Act. Together, the two laws form the Emergency Preparedness Act. The current Emergency Preparedness Act and its predecessor of the same name (1080/1991) were designed to replace the emergency provisions previously scattered over several different acts.

Iceland: The Icelandic constitution provides no mechanism for the declaration of war, martial law nor state of emergency.

India: There is no implicit mention of Martial Law in the Indian constitution with the exception of Article 34 which gives Parliament the power to indemnify persons in respect of acts done in territories where martial law was in force and to legitimize such actions. But in the text itself, there is no mention of any grants of power to declare Martial Law.
During the British Raj, Martial law was effectively declared in the Defense of India Act, 1915 and the Defense of India Act, 1939. It was also declared in most of the Punjab during 1919 as a response to tensions caused by the Amritsar Massacre. These tensions were caused due to the controversial Rowlatt Act.

Indonesia: On 18 May 2003, during a military activity in Aceh, under the order of the president, Indonesian Army Chief imposed martial law for a period of six months to eliminate Acehnese separatists.

Iran: On 7 September 1978, in response to public demonstrations protesting the perceived government involvement in the death of the son of Ayatollah Khomeini, Mostafa Khomeini, Shah Mohammad Reza Pahlavi appointed Chief of Army Staff General Gholam Ali Oveisi as the military governor of the capital city of Tehran. On 8 September, the government effectively declared martial law on the capital along with several other cities throughout the country, after which further protests erupted that lead to the army opening fire on a group of protesters in Tehran's Jaleh Square on the same day. Estimates on the number of casualties vary; However, according to Iranian human rights activist Emadeddin Baghi, the number of people killed was 88 of which 64 were gunned down in Jaleh Square. The day is often referred to as Black Friday. Unable to control the unrest, the Shah dissolved the civil government headed by Prime Minister Jafar Sharif-Emami on 6 November and appointed General Gholam Reza Azhari as the prime minister whom ultimately failed in his efforts to restore order to the country. As he was preparing to leave the country, the Shah dissolved the military government and appointed Shapour Bakhtiar, a reformist critic of his rule, as the new prime minister on 4 January 1979. Bakhtiar's government fell on 11 February and gave rise to the Islamic Republic and the creation of a new constitution.
Article 79 of the Constitution of the Islamic Republic of Iran forbids the proclamation of martial law without the approval of the Islamic Consultative Assembly.

Ireland: In 1916, during the Easter Rising, Lord Wimborne the Lord Lieutenant of Ireland, declared martial law to maintain order in the streets of Dublin. This was later extended both in duration and geographical reach to the whole of the country with the consent of the United Kingdom of Great Britain and Ireland government. Much of Ireland was declared under martial law by the British authorities during the Irish War of Independence. A large portion of Ireland was also under de facto martial law during the Irish Civil War. 
In late July 1921 Lord Cave (House of Lords) ruled on an appeal that:"...the military court, the validity of whose sentence was called into question, was a body possessing no statutory or common law authority...". The Court of Chancery (Ireland) also ruled that the Restoration of Order in Ireland Act 1920 had superseded the power to declare martial law. Any sentences by military tribunals that were not in accordance with that Act were declared void.
The current Irish Constitution allows for martial law if the government declares a state of emergency; however capital punishment is prohibited in all circumstances, including a state of emergency.

Israel: Military administrative government was in effect from 1949 to 1966 over some geographical areas of Israel having large Arab populations, primarily the Negev, Galilee, and the Triangle. The residents of these areas were subject to martial law. The Israel Defense Forces enforced strict residency rules. Any Arab not registered in a census taken during November 1948 was deported. Permits from the military governor had to be procured to travel more than a given distance from a person's registered place of residence, and curfew, administrative detentions, and expulsions were common. Although the military administration was officially for geographical areas, and not people, its restrictions were seldom enforced on the Jewish residents of these areas. In the early 1950s, martial law ceased to be in effect for those Arab citizens living in predominantly Jewish cities of Jaffa, Ramla, and Lod, constituting a total of approximately 15% of the Arab population of Israel. But military rule remained in place on the remaining Arab population elsewhere within Israel until 1966.
This period is remembered for its extreme crackdown on political rights, as well as unaccountable military brutality. Most political and civil organization was prohibited. Flying of Palestinian flag, as well as other expressions of Palestinian patriotism were prohibited. Furthermore, despite theoretical guarantee of full political rights, military government personnel frequently made threats against Arabs citizens if they did not vote in elections for the candidates favored by the authorities. Perhaps the most commemorated incidence of military brutality in this time period was the Kafr Qasim massacre in 1956, in which the Israel Border Police killed 48 people (19 men, 6 women and 23 children aged 8–17) as they were returning home from work in the evening. The Israeli army had ordered that all Arab villages in the proximity of the Green Line be placed under curfew. However, this order came into effect before the residents of these localities, including residents of Kafr Qasim, were notified.
Following the 1967 war, in which the Israeli army occupied the West Bank, Gaza Strip, the Golan Heights in Syria, and the Sinai Peninsula in Egypt, martial law over the Palestinian population as well as the Jordanian, Syrian, and Egyptian populations in these areas was put in place. In 1993, the Oslo I agreements facilitated limited self-rule for Palestinians under the Palestinian National Authority. Officially, only parts of Area C in the West Bank are under martial law.
During the 2006 Lebanon war, martial law was declared by Defense Minister Amir Peretz over the north of the country. The Israel Defense Forces were granted the authority to issue instructions to civilians, and to close down offices, schools, camps and factories in cities considered under threat of attack, as well as to impose curfews on cities in the north.
Instructions of the Home Front Command are obligatory under martial law, rather than merely recommended. The order signed by Peretz was in effect for 48 hours and was extended by the Cabinet and the Knesset Foreign Affairs and Defense Committee over the war's duration.

Mauritius: Mauritius is known as being a "Westminster" style of democracy but a peculiar system that was imposed in Mauritius during a period of civil unrest in 1968 as an emergency measure, has never been repealed and is still used by the police force there to this day. The system, which has no apparent foundation in the constitution of Mauritius, enables the police to arrest without having to demonstrate reasonable suspicion that a crime has been carried out but simply on the submission of "provisional information" to the magistrate. The accused is then placed on remand or bail and required to report to the police or the court on a regular basis, sometimes every day. There are examples of this system being used to intimidate or coerce individuals in civil litigations.

Myanmar: On 1 February 2021, democratically elected members of Myanmar, known as the National League for Democracy, were overthrown by Myanmar's military, called the Tatmadaw. This military placed their power in a military junta. Five days following the coup, factory workers around Yangon (a region in Myanmar) held protests against the coup regime. On 14 March, security forces killed upwards of sixty-five protestors in the town of Hlaingtharyar.
