Introduction {#introduction}

When police finish questioning a suspect but need more time to investigate, they have two main options: Release Under Investigation (RUI) or pre-charge police bail. Understanding the difference between these is crucial, as they have significantly different legal implications and time constraints.

This guide explains both procedures, their legal basis, key differences, and what they mean for suspects awaiting charging decisions.

What is Release Under Investigation (RUI)? {#rui}

Definition

Release Under Investigation (RUI) was introduced by the Policing and Crime Act 2017,[1] which amended PACE to allow suspects to be released without bail conditions while investigations continue.

How It Works

When RUI is used:

• Police have finished initial questioning
• Further investigation needed before charging decision
• Police determine bail is not necessary
• No conditions or restrictions imposed

What happens:

• Suspect released from custody with no conditions
• Investigation continues in background
• No requirement to return to police station on specific date
• Police will contact when investigation complete

No time limits: Unlike pre-charge bail, there are no statutory time limits on RUI.[2] Cases can remain under investigation indefinitely, though the College of Policing recommends regular reviews.

Advantages of RUI

✓ Freedom: No bail conditions restricting your life
✓ No geographical restrictions: Can live and travel freely
✓ No curfews: No restrictions on your movements
✓ No contact restrictions: Unless separate court orders exist

Disadvantages of RUI

✗ No time limits: Investigation can continue indefinitely
✗ Uncertainty: No set date to return for update
✗ No automatic reviews: Unlike bail, no mandatory review periods
✗ Difficult to challenge: No mechanism to review or challenge RUI

What is Pre-Charge Police Bail? {#bail}

Definition

Pre-charge police bail is governed by PACE sections 47 and 47ZA-47ZM (as amended by the Policing and Crime Act 2017).[3]

How It Works

When bail is used:

• Police determine bail is necessary and proportionate
• Need to prevent specific risks (further offending, witness interference, absconding)
• Investigation ongoing
• Conditions may be required

What happens:

• Released from custody with or without conditions
• Required to return to police station on specified date ("bail return date")
• Conditions can include:
  • Residential requirements (live at specific address)
  • Curfews
  • Non-contact orders (stay away from victims/witnesses)
  • Geographical exclusions
  • Reporting requirements
  • Surrender of passport

Bail Time Limits

Strict time limits apply under PACE as amended by the Police, Crime, Sentencing and Courts Act 2022 (in force 28 October 2022):[4]

Initial applicable bail period (ABP): Up to 3 months in standard cases

• Authorised by the custody officer
• (For FCA, SFO, NCA or HMRC cases the initial ABP is 6 months)

First extension: Up to 6 months (total)

• Authorised by an officer of at least Inspector rank
• Must be necessary and proportionate, with the investigation conducted diligently and expeditiously

Second extension: Up to 9 months (total)

• Authorised by an officer of at least Superintendent rank
• Same conditions apply

Beyond 9 months:

• The police must apply to the magistrates' court (PACE ss.47ZF-47ZJ; Crim PR 14.21-14.22)[5]
• The court may extend (typically to 12, 18 or 24 months in exceptionally complex cases) only where the investigation is being conducted diligently and expeditiously and the extension is necessary and proportionate

Key Differences {#differences}

Time Limits {#time-limits}

RUI Timescales

No statutory limits exist.[6]

However:

• Investigations should be conducted expeditiously
• Unreasonable delay may constitute abuse of process
• College of Policing recommends regular reviews
• Can make representations to police about delays

Pre-Charge Bail Timescales (from 28 October 2022)

Standard cases (PCSC Act 2022, Sch. 4; PACE ss.47ZB–47ZJ):

1. Initial applicable bail period (ABP): up to 3 months — custody officer
2. Extension to 6 months: inspector (statutory conditions A–D met)
3. Extension to 9 months: superintendent
4. Beyond 9 months: police must apply to the Magistrates' Court (Criminal Procedure Rules Part 14)

(For FCA, SFO, NCA or HMRC designated cases the initial ABP is 6 months.)

Important: Do not assume bail simply "automatically ends" if a deadline is missed — the current PACE provisions and Home Office statutory guidance govern what happens next. Take advice on the live position.[7]

Legal Implications {#implications}

Employment

RUI:

• No formal restrictions
• May need to inform employer (depends on contract)
• No automatic disclosure obligations

Bail:

• Conditions may impact employment (curfews, geographical restrictions)
• Some conditions must be disclosed to employer
• Breach of bail is criminal offence

Travel

RUI:

• Free to travel (unless passport separately seized)
• No restrictions

Bail:

• May have condition to surrender passport
• May have condition not to leave jurisdiction
• Breach is criminal offence

Further Offending

RUI:

• Not subject to conditions
• Any further offending charged separately

Bail:

• Conditions designed to prevent further offending
• Breach of bail conditions is separate criminal offence
• Can be arrested for breach

Your Rights {#rights}

Rights Under RUI

✓ Right to legal advice throughout
✓ Right to make representations about investigation delays
✓ Right to be informed of charging decision
✓ Right to complaint if investigation unreasonably delayed

Rights Under Bail

✓ Right to legal advice
✓ Right to challenge bail conditions
✓ Right to vary conditions if circumstances change
✓ Right to be told reasons for conditions
✓ Right to challenge extensions at magistrates' court (if beyond 6 months)
✓ Right to bail to end if time limits breached

Summary {#summary}

Release Under Investigation (RUI):

• Introduced 2017 to reduce use of bail
• No conditions or restrictions
• No statutory time limits
• Cannot easily challenge or review
• Appropriate for lower-risk investigations

Pre-Charge Police Bail:

• Used when conditions necessary
• Strict time limits and review periods
• Can be challenged at each stage
• Conditions can restrict daily life
• Breach is criminal offence

Key Takeaway:
RUI gives more freedom but less certainty. Pre-charge bail has restrictions but defined timescales and review points.

Both can only be used while investigation continues. Once police have sufficient evidence, they must either:

• Charge the suspect
• Release with no further action (NFA)
• Offer an out-of-court disposal (caution, conditional caution, etc.)
