The writ was entered in the minute book of the Talmud Torah congregation of Amsterdam and no act rescinding it has been catalogued here. The ban was of a kind that could be lifted on submission, and Spinoza never submitted. Proposals to lift it have been raised publicly in modern times, and the atlas has not verified a decision in either direction, nor identified who would have the standing to make one now.
What would resolve this The minute books of the Amsterdam Portuguese Jewish congregation for any later entry on the case, or a statement from the congregation or its rabbinate. A finding that no such act exists is equally useful and would close the question.
