Apple slams EU as epic court battle over tax bill begins

The commission's "conclusion... is wrong," he added.

The commission's historic decision was delivered in August 2016 by Competition Commissioner Margrethe Vestager, a shock decision that put Europe at the forefront of an emerging effort to rein in the power of US big tech.

Lawyers for the world's biggest company faced EU officials in the Luxembourg court, challenging a decision that CEO Tim Cook slammed at the time as "total political crap".

Ireland, which is similarly appealing against the decision, also testified at the start of two days of hearings, and lashed out at the EU's "astonishing" interpretation of tax law.

"The Commission decision simply ignores Irish laws," Ireland's representative Maurice Collins told judges.

The EU accuses Apple of parking untaxed revenue earned in Europe, Africa, the Middle East and India in Ireland, which has become a European hub for US-based big tech.

This privilege allegedly gave Apple an advantage over other companies, allowing it to avoid taxes between 2003 and 2014 of around 13 billion euros which, according to Brussels, constituted illegal "state aid" by Ireland.

The judges are not expected to hand down their decision before 2020 and any appeal would then go the EU's highest court, the European Court of Justice, for a final ruling that could land as late as 2021.

- 'Rewrite history' -

Apple fiercely denies the tax bill. The US government also insists the order by Brussels constitutes a major breach of international tax law.

"The European Commission has tried to rewrite Apple's history in Europe, to ignore Ireland's tax laws and, in doing so, to disrupt the international tax system," Tim Cook said in an open letter in 2016.

The group insists that it is in the United States, where the company invests in research and development and thus creates wealth, that it must pay taxes on the revenue in question.

This became possible after a major tax overhaul in the US at the end of 2017 that allowed Apple to repatriate profits made abroad. Apple has promised to pay Washington a tax bill of $37 billion, in addition to the taxes already paid in the United States.

The two days of hearings are taking place in a tense trade context between the EU and the United States where President Donald Trump accuses Europeans of deliberately attacking American technology giants.

The EU's Competition supremo, Vestager, is in particular accused by the US president of "hating" the US. He has slammed her as the "tax lady" because of the investigations and heavy fines imposed on US groups such as Google.

Pending the conclusion of the case, Apple has blocked the funds in an escrow account: a total of 14.3 billion euros after interest.

The group, which has been present in Ireland since the 1980s, employs around 6,000 people in Cork, the country's second-largest city.

The first indications of how the Apple case may finish will come as early as September 24 when the same EU court will rule on whether the Vestager was right to demand unpaid taxes from Starbucks and a unit of Fiat Chrysler.
