The State of Texas must submit its brief this month to a federal appeals court in a case about a waiver to an Israeli anti-boycott clause that was struck for a Houston engineering firm.

The anti-boycott clause, which is a protectionist oath for Israeli commerce, is ubiquitous in government contracts in Texas. From the smallest school districts and county offices to the largest cities, public universities and state agencies, any company with 10 or more full-time employees bidding on contracts valued at over $100,000 must swear in writing not to boycott any Israeli economic activity.
