The claim was brought by two of Worboys' earliest victims, who reported attacks to the police in 2003 and 2007.
Amid concerns over the potential impact of new lawsuits on stretched forces, the National Police Chiefs' Council spokesperson said it was right for those let down to seek redress.
Mr Petherbridge added: "This is a significant decision for the families of Anthony, Gabriel, Daniel and Jack".
The two victims brought claims against the Met Police under Article 3 of the Human Rights Act, which sets out the right not to be subjected to torture or to inhuman or degrading treatment. Therefore, I would expect today's judgment to have a positive bearing on our case.
A total of 17 officers are being investigated by the IOPC over the case, seven of whom could face the sack if found to be guilty of gross misconduct.
Mr Petherbridge said: "I do accept that in times of cutbacks police can not do anything they want to do but a lot of the cases I'm instructed in money isn't the whole picture".
The top court upheld a lower court's decision to award compensation to two victims of serial rapist John Worboys, who is believed to have attacked more than 100 women over many years. "We will now consider the full implications of the judgement and what it could mean for investigations in the future".
The deputy commissioner of the Met, Sir Craig Mackey, said: "We have always accepted that serious mistakes were made in this investigation and it was only the courage of the victims coming forward, including these two claimants, that enabled us to finally convict Worboys".
He said the force might have to shift resources from other crimes, such as fraud, to investigate serious violent crime. "There is no doubt that it will have implications for how we resource and prioritise our investigations". However, the police later appealed saying they shouldn't be held accountable in these kinds of cases. We have always been clear that the appeal to the Supreme Court was not based on factual differences between us and the victims, but on the appropriate interpretation of European human rights law.
