The University as well as the Presbyterian Church raise some interesting legal issues.
First, the fiduciary duty of those directing investment based on political criteria. There's an opening for the legal community here, since investment decisions are always judged in retrospect.
And the similarity of the UW's actions to the Arab boycott of Israel. Participating in the Arab boycott is illegal. It would appear to me to be a fine line.
The UW boycott may be a fine line. In my opinion the PCUSA has clearly crossed the line. The anti-boycott law prohibits joining a foreign boycott. In the case of the PCUSA, there is an existing anti-Israel boycott, and the decision of the executive council (whatever they call themselves) was taken after a presentation by a Palestinian Arab at the national meeting, thereby tying the boycott to foreign influence.
I hope someone brings suit agains the Church for violating federal law.
