The illegal immigration minister has denied suggestions the government is hamstrung over how to manage the claims of tens of thousands of asylum seekers.
The statement revealed the legislation has banned the government from granting asylum to anyone arriving illegally on or after 7 March last year.
But new laws requiring their deportation only became effective from 20 July.
It leaves the claims of more than 22,400 people in apparent legal limbo.
Minister Michael Tomlinson said the Rwanda plan, which the Supreme Court ruled unlawful in November, will give the government a way to deal with the claims.
The Minister added: “The bill, when it comes in means that we can get planes off the ground, so we need to get that bill to come through.”
Mr Tomlinson said the bill, which is making its way through parliament, would apply to asylum seekers already in the UK.
Asked whether he would guarantee planes carrying asylum seekers would take-off for Rwanda, Mr Tomlinson replied “yes”.
“Yes, we need to get through the bill first, yes we need to get the treaty ratified, and then the planes will take-off.”
Prime Minister Rishi Sunak last week shook hands on a £1000 bet with TV host Piers Morgan that flights would depart before the next election.
In a recent report, it claimed a contradiction in the government’s small boats policy left the Home Office powerless to deport or grant asylum to 22,448 asylum seekers who arrived between March and July.
The government is legally required to house and support the asylum seekers while their claims are being processed, costing taxpayers millions of pounds each day.
Mr Tomlinson said a “decision to pause” was taken while the government mulled over how to respond to the Supreme Court ruling.
Home Secretary James Cleverly said a new treaty with Rwanda signed in December addressed the court’s concerns.
Labour has sharpened its line of attack on migration, laying the blame for a third of all boat arrivals since January 2018 at the feet of Rishi Sunak.
More than 38,000 small boats have crossed the English Channel since he became prime minister, according to figures circulated by Labour.
“By focusing solely on getting off a few symbolic flights to Rwanda at massive cost to the taxpayer, he has taken his eye off the vital task of stopping the criminal smuggler gangs,” shadow home secretary Yvette Cooper said.
