The Chair should run through these points with the speaker, using discretion according to the circumstances
The LSE Ground rules states that the School exists for the pursuit of learning. Its fundamental purpose can be achieved only if its members, and visitors to it, can work and conduct their business peacefully in conditions which permit freedom of thought and expression within a framework of respect for the rights of other persons.
In pursuance of its duties under section 43 of the Education (No.2 ) Act the School has adopted a Code of Practice on Free Speech to ensure that freedom of speech within the law is secured for students, employees, other members of the School and for all persons School premises, including visiting speakers.
Every member of and associated with the School, including visiting speakers, shall be entitled to freedom of thought, conscience and religion, to hold opinions without interference, disability, or disadvantage, and to freedom of expression within the law, including the right to seek, receive and impart information and ideas.
The School has the right to refuse an event or to close an event once it has begun in circumstances where the bounds of lawful free speech are exceeded or thought likely to be exceeded. A breach of lawful free speech is not easy to define in principle but may occur if there is abusive, offensive or racially offensive behaviour or language or incitement to commit crime or a breach of the peace; or where physical harm to persons, or damage to the School property or a breach of the peace is taking place or thought likely to take place. The event may also be closed if, in the opinion of the School authorities, unlawful acts are likely to take place, or indeed, are taking place, as a result of the event in question.
