The possibility to request that a certain species is added to or removed from the Positive List is a mandatory requirement set by EU Law. This possibility to request a change to the list should be enshrined in the Law or a regulation, the decision-making should be done within a reasonable timeframe, and the decision should be open to appeal in court. It depends per country how this procedure is set up. In Belgium, anyone can request that a species is added to or removed from the Positive List. They charge a fee of 60 EUR for each request to deter non-serious requests. A request has to be motivated and substantiated, by adding sufficient objective scientific data that indicates that the species concerned is suitable to be kept as pet by any layman. The Minister will take a decision on the request within six months. In the Netherlands, a similar procedure is expected.
