THAT Edward Snowden was elected rector of the University of Glasgow demonstrates the importance of freedom of expression to its students.

But academic freedom carries with it responsibilities. Today the University of Glasgow greeted the Israeli Ambassador "as a welcome guest to the School of Law". It did so under an unprecedented cloak of secrecy.

We are saddened by the invitation and believe it should not have been extended. The state of Israel has effectively silenced legitimate expression by Palestinians through limiting their movement, appropriating their land and violating their rights, in ways that are well documented. Gaza is in ruins, Israeli universities are being built on land which has been settled illegally. Israeli Embassy security are today on campus. This puts staff involved in projects in the Occupied Palestinian Territories at risk.

The setting aside of the normal decision-making procedures about events has encouraged hurried protest. The visit risks damaging existing relationships which staff across the university have built carefully with groups in Palestine and elsewhere internationally, who will be distressed to hear about this visit.

In this we have a concern for the postgraduate students in the School of Law. We understand that as of Friday lunchtime, students did not know who would be speaking. It is seriously concerning that students who may wish to follow the National Union of Students position on the Call for an Academic Boycott, Divestment and Sanctions are being denied the information which would make it possible for them to do so.

It is a matter of grave concern to us that students who were invited to attend the event at the University of Glasgow were not given the necessary time to prepare for the seminar, and to consider, analyse and discuss the implications. Instead we believe the withholding of information will seriously disadvantage students and place them in a position of vulnerability.

We believe this constitutes a failure in our duties as academics. It is our view that part of the responsibility for the conduct of academic freedom is that time and preparation need to be accorded for reading, preparation and debate, most especially in difficult matters where there is considerable, known disagreement. When this is withheld there is a tendency for chaotically organised positions to emerge and for students to be left at a serious disadvantage. Whilst the School of Law has urged discretion it is not the stated position of the guest. It is a stated position of the Israeli Ambassador, when faced with protest, to engage in even more "active reaching out and making our case".

Either senior management in the university and decision-makers in the School of Law have stumbled into a deadly conflict and diplomatic game, and have been played, or they have taken the side of a powerful aggressor. The decision-makers and university leaders have breached the trust of their staff and students with respect to the responsibilities that rest with them as stewards of something as precious as the right to academic freedom.
