PHR (Amendment) (no.22) came into operation at 00.01 on 22 January 2022, although I did not find it publicly available until the morning of the 24th.
The age at which a child travelling with a person covered by the vaccination exemption is required to test in order to leave isolation early is changed from 12 years to 12 years and three months (amended reg.5B).
Reg 6A is revoked. This formerly required wearing of face coverings on vehicles “used to provide a public transport service”. These amending Regulations do not, however, amend Reg 6B, introduced at the same time as Reg 6A, and used to require face coverings in public health settings through a GC (GC 2021/0094). Removing the PHR requirement to wear face coverings in these settings was announced as coming into effect at 00:01 on the 22nd of January.
A GC has legal effect, so if its provisions are no longer desired, the approach throughout the pandemic has been to repeal them, if they did not contain a built in time limit. A recent example is the GC giving CoMin the power to define countries in different categories (GC 2021/0089) which revoked an early GC setting out a change of category for France (GC 2021/0086).
The face coverings in public health settings GC did not contain a sunset clause, but was revoked by GC 2022/0013, which was not available on the Tynwald website as of noon on the 25th of January, but which can be found here. The text of GC 2022/0013, as of noon on the 25th, was not findable by google search, or linked from covid19.gov.im or (according to OpenLinkProfiler) linked to from any webpage anywhere else. As I’ve said before, making legally binding documents available to the public before they come into effect is profoundly important. More than three days passing before a member of the public can find the law does not reflect this.
