In my opinion, here "intended" is used as a synonym of the term "planned".

Here's an extract from the Civil Procedure Rules (i.e. nothing to do with criminal law)

http://www.justice.gov.uk/courts/procedure-rules/civil/rules...
PRACTICE DIRECTION 25A – INTERIM INJUNCTIONS This Practice Direction supplements CPR Part 25

Urgent applications and applications without notice

4.4

Applications made before the issue of a claim form:

(1) in addition to the provisions set out at 4.3 above, unless the court orders otherwise, either the applicant must undertake to the court to issue a claim form immediately or the court will give directions for the commencement of the claim5,

(2) where possible the claim form should be served with the order for the injunction,

(3) an order made before the issue of a claim form should state in the title after the names of the applicant and respondent ‘the Claimant and Defendant in an Intended Action’.

****

i.e. because the claim form is not issued yet the action is therefore "intended" or planned (that's how I read it).

In terns of translation I'd suggest:

intended - запланована / призначена
action - позова, судова справа
