The UK government must notify Brussels under the 'Authorisation Directive' (98/34/EC) of upcoming changes to 'technical standards' that might affect cross-border trade, e.g. in the provision of telecommunications services. For more information on EC notification see my blog on the 2 remaining pieces of legislation required for the file sharing clamp-down under the Digital Economy Act.
If you're not quite following I don't blame you; what it does mean is that things could get very interesting. The UK has to ask EC for permission to re-enact an EU law the ECHR struck down as incompatible with our Human Rights.
It also means at least a 90-day window before it can become law.
Interesting times - and also interesting to note the parallel debate from parts of the establishment pushing to distance ourselves from Europe and leave the European Convention on Human Rights.
