The head of a powerful US antitrust law firm says the search giant is “not here to lecture” its competitors.
Lawyers for Google and the Electronic Frontier Foundation, which represent both the tech giants, have been fighting a series of antitrust laws that they claim will lead to the breakup of their companies.
The battle has been going on for years, but the outcome of the Supreme Court’s landmark ruling on Monday could finally bring an end to the long legal battle.
The US Supreme Court ruling will be used as a basis for other countries to take similar action, with Google and Facebook among those who have made their case to the high court.US President Donald Trump has threatened to veto legislation that would have forced him to accept the Supreme Courts decision.
The White House says Mr Trump is “open to considering and debating any legislative measures that may advance the economic interests of our country”.
“We are also reviewing the President’s actions to ensure that any steps taken are consistent with our core values,” a White House spokesperson said in a statement.
“The President will make the final determination of his future course of action on the issues raised by this case.”
It is the latest in a string of legal battles between Google and other tech giants.
In April, the US Supreme court ruled against a Google antitrust case brought by the company.
The high court also upheld a 2015 decision by the Federal Trade Commission to fine the search company $1bn for failing to disclose how much of its market share was held by US companies, which were the dominant players in search advertising.
The search giant’s appeal of that ruling was later upheld.
It followed a 2015 ruling by the US Court of Appeals for the District of Columbia Circuit, which found that Google’s antitrust violation was not just the product of “one single, single, isolated act” but also “was pervasive”.
A case brought against Google by Apple was also dismissed in 2016.
In December 2016, the European Union ruled that Google should be required to reveal how much its search engine paid publishers, and to reveal to its customers whether it was using its advertising technology to target them.
In June 2017, the New York state attorney general filed a civil lawsuit accusing Google of a “pattern and practice” of abusing its market dominance in search and advertising by illegally restricting competition in the marketplace.
The company has argued that the EU’s decision was wrong and the court had not done enough to hold Google to account.
The European Commission said in November that it was taking the issue up with the US Justice Department.
“We intend to pursue the case with a view to bringing this matter before the European Court of Justice, and, if that cannot be done, we will consider other legal avenues,” the commission said in October.
The Supreme Court decision is likely to have a significant impact on the tech companies’ business plans.
In October, Google said that it would stop using the ad network Google AdWords in a bid to make it easier to target customers with targeted ads.
The decision means Google will have to use its own network of search engines to deliver its targeted ads to customers.
