Home Secretary Alan Johnson has ordered a wholesale review of the control orders regime.
Lord Carlile, the independent reviewer of terror legislation, will consider if the regime is still "viable" following a ruling by the House of Lords.
The court ruled last year that terror suspects placed on control orders, which restrict their movements and who they can see, should be told about secret evidence used against them.
Following the judgment, one man - known as AF - had his order revoked because Mr Johnson said it was not in the national interest for the evidence to be made public.
He said: "My current assessment is ... that the control order regime remains viable following the House of Lords judgment and that the national security reasons for maintaining the regime have not changed.
"However, as further control order cases are considered by the courts during the autumn, I will be keeping this assessment under review.
"In addition to this ongoing review within my department, I have asked the independent reviewer of the Prevention of Terrorism Act 2005, the Lord Carlile of Berriew QC, to review the impact of the House of Lords judgment and to advise me as to whether the assessment that the regime remains viable is right."
In his quarterly update to Parliament, Mr Johnson said five control orders were revoked between June 11 and September 10, including AF. He said only the case of AF was as a "direct result" of the House of Lords judgment.
Three other individuals had their orders revoked because he said they were "no longer necessary". The remaining individual is being deported.
