“[24] The first question should therefore be answered to the effect that a national court which is called upon, within the limits of its jurisdiction, to apply provisions of Community law is under a duty to give full effect to those provisions, if necessary refusing of its own motion to apply any conflicting provision of national legislation, even if adopted subsequently, and it is not necessary for the court to request or await the prior setting aside of such provision by legislative or other constitutional means.”
“[21] In the absence of a Community provision prescribing the period during which Community nationals seeking employment in a member-State may stay there, a period of six months, such as that laid down in the national legislation at issue in the main proceedings, does not appear in principle to be insufficient to enable the persons concerned to apprise themselves, in the host member-State, of offers of employment corresponding to their occupational qualifications and to take, where appropriate, the necessary steps in order to be engaged and, therefore, does not jeopardise the effectiveness of the principle of free movement. However, if after the expiry of that period the person concerned provides evidence that he is continuing to seek employment and that he has genuine chances of being engaged, he cannot be required to leave the territory of the host member-State.”
“… In this case, the Union citizens and their family members may not be expelled for as long as the Union citizens can provide evidence that they are continuing to seek employment and that they have a genuine chance of being engaged.”
“The central starting point in this matter is to recognise that within the law of Scotland there are only two standards of proof to apply in civil and criminal proceedings, namely the balance of probabilities and beyond reasonable doubt respectively and there is no room for any suggestion that some form of intermediate standard between those two applies in certain circumstances. Whatever, therefore, may be the context of so called quasi-criminal or penal proceedings, the standard to be applied must be one of these two. I am not satisfied that certain dicta in the English cases presented to us would suggest that the law of England is any different. In so far as there are references to probabilities, I consider them to be dealing with the weight and quality of evidence which might be required in a certain context rather than defining the relevant standard of proof to be applied. The same can be said of certain observations in Mullan v Anderson. As to the evidence that might be required to reach a conclusion upon a standard of balance of probabilities in any particular case must depend upon the circumstances of that case and its subject matter, and I do not find it helpful to seek to define the matter any further.”
