THE STATE OF THE EUROPEAN UNION

4. Preserving the Union’s autonomy as regards
its decision-making as well as the compe-
tence of the Court of Justice of the European
Union. This principle reflected the need to
maintain the unity and integrity of EU and
avoid concessions that might allow a third
country to rupture that cohesion. Negotiators
were particularly anxious to prevent non-
Member States from playing a role in institu-
tional decision-making processes and to pre-
serve the EU Court of Justice’s monopoly on
the interpretation and application of EU law.
These principles, which appeared in the ne-
gotiation guidelines approved by the Council on
22 May 2017, formed the basis of the EU nego-
tiator’s mandate

. Each laid out in detail the is-
sues to be covered in the negotiation agenda
and that needed to be addressed on the final
withdrawal treaty.
European institutions were thus prepared to
begin the phase I of the negotiations. This
would nevertheless happen later than expected
due to Teresa May’s decision to call a snap gen-
eral election on 8 June 2017 in a bid to strength-
en her political position at home before em-
barking upon negotiations. May, who was
picked by her party to be Prime Minister in July
2016 following the resignation of David
Cameron, saw an early election as a means of
gaining a healthy majority in the House of
Commons in favour of withdrawal and shoring
up her negotiating position with the EU. Her in-
tentions were frustrated by the results, which
left her short of a parliamentary majority, forced
her to form a minority government with the
support of the Northern Ireland Democratic

Withdrawal negotiations, which did not get
officially underway until July 2017, began with
a series of four-day sessions held in Brussels
spaced approximately a month apart. First on
the agenda were issues related to withdrawal
that the European Council had determined
needed to be addressed during phase I, which
included the rights of EU citizens in the UK and
UK citizens in the EU, the settlement of out-
standing financial commitments assumed by
the UK as a member of the EU (popularly re-
ferred to as the “Brexit bill”), the future status
of the border between Ireland and Northern
Ireland, the governance of the agreement and a
range of other technical matters. It was estab-
lished that the European Council would assess
what had been achieved during these sessions
in October and decide whether to give the
green light to move on to phase II of the nego-
tiations on the basis of progress made.
Negotiations conducted that summer and
fall produced little in the way of progress but a
fair amount of mutual sniping consisting mainly
of European charges that British negotiators
had come to the table unprepared and British
counter charges of European inflexibility.
Theresa May attempted to break the deadlock
by giving a speech in Florence in September
meant
to provide new impulse for the process

Under May’s leadership, the Conservative Party won 318
of the 650 seats contested, 12 fewer than it had won in
the previous general election held in 2015. Having lost her
absolute majority, in order to remain Prime Minister, May
was forced to strike an agreement on 26 June 2017 with
the Democratic Unionist Party of Northern Ireland, which
supported a “hard Brexit” solution.
