Overview

The table below shows information about opinion requests we have received in 2020 and what stage each request has reached.

For example, you can see whether:

  • you can file observations on a request or whether the period for doing so has expired
  • we have issued an opinion
  • the person who filed the request has withdrawn it
  • we have refused a request for an opinion. Where we’ve issued a decision refusing the request, you can view this in our decisions database
