Who was the Boston lawyer to opposed the writes of assistance?

The Boston lawyer who opposed the writs of assistance was James Otis. In 1761, he delivered a passionate argument against these general search warrants, which allowed British customs officials to search colonial homes and businesses without specific cause. Otis contended that such practices violated natural rights and the principles of liberty, laying the groundwork for American resistance to British authority. His stance significantly influenced colonial attitudes toward British governance and helped spark the American Revolution.
