This does not change the fact that the UK will be leaving the European Union, he said.
The government is hoping to publish the bill on Thursday but there is a possibility it could slip beyond that.
Davis said the legislation would be narrow, focusing only on the question of triggering article 50, and warned that it must not be used as a vehicle for attempts to thwart the will of the people, or frustrate or delay the process of our exit from the European Union.
This will be the most straightforward bill possible, to give effect to the decision of the people and respect the supreme courts judgment, he added, stressing that it was not about whether the UK would leave the EU, because that had been decided by the June referendum.
Davis said government lawyers were scrutinising the long judgment, but made clear that he remained confident article 50 would be triggered by the deadline at the end of March.
This timetable has already been supported by this house, he said, saying the legislation would be separate to the great repeal bill.
Davis was urged by Brexiters in parliament to issue the legislation quickly and keep it short, but was also pressured by opposition figures and MPs on his own side to publish the governments Brexit plan as a white paper in order to allow further scrutiny.
The shadow Brexit secretary, Keir Starmer, said: Labour accepts and respects the referendum result and will not frustrate the process. But we will be seeking to lay amendments to ensure proper scrutiny and accountability throughout the process. That starts with a white paper or plan.
A speech is not a white paper or plan, and we need something to hold the government to account throughout the process. You cant have a speech as the only basis for accountability for two years or more.
Starmer was backed on the issue by Labours Hilary Benn, who chairs parliaments Brexit committee, and a series of Conservative backbenchers including Ben Howlett who said: I believe that the government should publish a white paper in order to enable my constituents to have their views heard.
