63. 此外，来文方称，被逮捕者被隔离关押了三至五天不等。鉴于政府选择不反驳这一指控，工作组认为这一指控是可信的。关于隔离关押本身，工作组回顾指出，这意味着被逮捕者与外界，包括其家人和律师没有联系，无法获得援助。因此，被拘留的学生无法行使权利质疑其逮捕的合法性、适当性和必要性，这违反了《公约》第九条第四款。
63. The source maintains that the arrested persons were held incommunicado for a period ranging from three to five days. The Government has chosen not to refute this allegation, which the Working Group considers to be credible. The Working Group notes that the use of incommunicado detention means that the arrested persons had no contact with the outside world, including with persons such as family members or lawyers, who could have assisted them. They were therefore unable to exercise their right to challenge the lawfulness, appropriateness and necessity of their arrest and detention, in violation of article 9 (4) of the Covenant.
