Conspiracy to adapt wording from precedent for substantive offence is a serious offence related to premeditated theft/fraud.
As far as sentencing is concerned, (in the UK) if there are further charges brought against the perpetrators then this is likely to increase the term of sentence. Average sentence for this type of offence is upto 5 years in custody.
If the person comitting this offence had an unblemished character, and this was the only charge brought, then it could still be a considerable 3 years in custody.
