1. We will "reform" this or that institution of the EU
To carry out any meaningful reform beneficial to the UK, means obtaining a Treaty change. That requires unanimity. How do you get that, when a benefit to the UK means a disadvantage to another Member?

The only reform possible is tinkering on the edges that does not cause any form of discrimination, or change to the EU rules. Politicians use the word "reform" to cover the fact nothing will be done.

2. The EU Treaties are untouchable and are forever
The EU Treaties work through a British Act of Parliament. The Treaties are only valid as long as the Westminster Parliament allows. Britain's obedience to the Treaties rests solely with the Westminster Members of Parliament.

As no Parliament can bind its successor, neither a new Parliament, nor its Members, are bound to the Act through which the Treaties work. Any public annoyance concerning EU legislation should be directed to your MP. It is not the fault of the other Member States or the Commission.

Do not be put off by your MP saying it is beyond his/her responsibility. They use this as an excuse so as to get out of stating where they really stand.

3. To reverse any existing European Union legislation means leaving the EU
As EU legislation works through a British Act of Parliament, it is possible to amend that section of the Act, within domestic legislation, to close the drawbridge to that relevant section of the EU legislation, making it null and void in the UK.

For example, Westminster control of the UK fishing zone of 200 miles, or to the median line, does not necessitate leaving the EU. Some other Member States might not like it, but there is no mechanism within the EU rules for those States to force the UK out of the EU.

The UK Parliament can take back control (competency) of any area it likes. The legal and constitutional position is very clear. The decision rests in Westminster.

Some Westminster politicians shy away from that responsibility, stating that is not the case. If that happens you can be sure they support the creation of the European superstate, to which they are helping to deliver the United Kingdom in regional bite-size pieces.

4. To withdraw from the Common Fisheries Policies (CFP) requires the unanimous agreement of the EU Member States
No. It requires a majority vote in our Westminster Parliament, to create new legislation to amend the 1972 Act.

5. Even if we used domestic legislation to reverse EU legislation, we would be taken to the European Court of Justice (ECJ), and overruled
The jurisdiction of the ECJ in the UK is subject to the approval of the British Parliament, and therefore an appropriate clause excluding such jurisdiction could be inserted in the Act dis-applying the particular area of EU legislation, eg the CFP.
