Objection with regard to the reservation and statement made by Qatar upon accession: (May 20, 2019)
"The Government of the Portuguese Republic has examined the contents of the reservation to Article 3 and of the statement regarding Article 8 of the International Covenant on Economic, Social and Cultural Rights made by the State of Qatar.
The Government of the Portuguese Republic considers that the reservation to Article 3 of the International Covenant on Economic, Social and Cultural Rights is contrary to the object and purpose of the International Covenant on Economic, Social and Cultural Rights.
Furthermore, it considers that the statement regarding Article 8 of the Covenant is in fact a reservation that seeks to limit the scope of the Covenant on a unilateral basis.
The Government of the Portuguese Republic considers that reservations by which a State limits its responsibilities under [the] International Covenant on Economic, Social and Cultural Rights by invoking the domestic law or/and religious beliefs and principles [raise] doubts as to the commitment of the reserving State to the object and purpose of the Convention, as such reservations are likely to deprive the provisions of the Convention of their effect and are contrary to the object and purpose thereof.
The Government of the Portuguese Republic recalls that, according to customary international law as codified in the Vienna Convention on the Law of Treaties, a reservation incompatible with the object and purpose of the Covenant shall not be permitted.
Thus, the Government of the Portuguese Republic objects to these reservations.
This objection shall not preclude the entry into force of the Covenant between the Portuguese Republic and the State of Qatar."
Objection with regard to the declaration made by Myanmar upon ratification (September 7, 2018):
"The Government of the Portuguese Republic has examined the declaration made by the Government of the Republic of the Union of Myanmar to Article I of the International Covenant on Economic, Social and Cultural Rights and considers that it is in fact a reservation that seeks to limit the scope of the Covenant on a unilateral basis.
The Government of the Portuguese Republic considers that reservations by which a State limits its responsibilities under the International Covenant on Economic, Social and Cultural Rights by invoking the domestic law or/and religious beliefs and principles raise doubts as to the commitment of the reserving State to the object and purpose of the Convention, as such reservations are likely to deprive the provisions of the Convention of their effect and are contrary to the object and purpose thereof.
The Government of the Portuguese Republic recalls that, according to customary international law as codified in the Vienna Convention on the Law of Treaties, a reservation incompatible with the object and purpose of the Covenant shall not be permitted.
Furthermore, the Government of the Portuguese Republic does not share the interpretation of "the right of self-determination" expressed by the Government of the Republic of the Union of Myanmar which limits the content of this right and is not in line with the definition enshrined in International Law.
Thus the Government of the Portuguese Republic objects to this reservation.
This objection shall not preclude the entry into force of the Covenant between the Portuguese Republic and the Republic of the Union of Myanmar."
2004年10月13日提出的反对意见：
“葡萄牙政府认为有关一国通过一般性援引国家法律若干规定而限制其根据《经济、社会、文化权利国际公约》(ICESCR)应承担的责任可能会对保留国对公约的目标和宗旨作出的承诺提出质疑，此外也会损害国际法的基础。各国均希望，它们选择加入的条约的目标和宗旨得到各方的尊重，各国也准备为遵守这些条约规定的义务而进行必须的立法改革。
因此，葡萄牙政府反对土耳其对《经济、社会、文化权利国际公约》提出的保留意见。这种反对意见并不妨碍葡萄牙和土耳其之间的公约生效。”

1990年10月26日提出的反对意见：
“葡萄牙政府在此对阿尔及利亚政府在批准《公民权利和政治权利国际公约》和《经济、社会、文化权利国际公约》时作出的解释性说明正式表示反对。葡萄牙政府审查了上述声明的内容，认为这些声明可被视为保留意见，因此应视为无效，且与公约的宗旨和目标不符。
这种反对意见并不妨碍葡萄牙与阿尔及利亚之间的公约生效。”
