What is the current state of English law regarding the writ of sequestration?

In considering the current state of English law regarding the writ of sequestration, Baker J. referred to a similar case he had decided, Richardson v. Richardson, [1989] 3 All E.R. 779 at 783, where he had observed: Sequestration is an ancient tool of the law used as a last resort for enforcing orders of the court. Ancient tools need if possible to be adapted for use in modern conditions. In my judgment where otherwise the whole purpose of the sequestration would be defeated, the court is not constrained by ancient practice . . .
