The rule

English cases may persuade, but never bind.

Recap

Read the printing, the Contract Data and the governing law first

Three checks before you argue about any clause.

On Monday at work

  • Keep the Contract Data open beside the conditions.
  • Check the governing law (12.2) before you rely on a case.
  • Notify an unclear entry under 17.1 at once.

NEC4 kept the NEC3 rules on changes and the whole deal

Useful when you read a case decided under NEC3. Skip it if you are short of time.

Who must act as the contract states?

The Parties, the and the (10.1). Mutual trust is in 10.2, which is Module 2.

ECC 10.1, 10.2

What changed from NEC3?

NEC4 split the old 10.1 in two and dropped the words on gender from 12.1. For an NEC3 case, nothing changes in substance. 12.3 and 12.4 are the same in substance too.
