The unstoppable force paradox is an exercise in logic that seems to come up in the law all too often. There is a Chinese variant. The Chinese word for “paradox” is literally translated as “spear-shield” coming from a story in a Third Century B.C. philosophy book, Han Fiez, about a man selling a sword he claimed could pierce any shield. He also was trying to sell a shield, which he said could resist any sword. He was asked the obvious question and could give no answer.
The Washington Supreme Court broke the paradox between a 12-month moratorium during which the City of Woodinville considered sustainable development regulations for its R-1 residential area, and the efforts by the Northshore United Church of Christ (Northshore Church) to host a movable encampment for homeless people on its R-1 property.
