The 48 Hours After a California Arrest

The hours after an arrest are the part of a criminal case people understand least and remember most. Nobody explains the schedule while it is happening. You are told very little, the phone situation is bad, and the one number everybody half-remembers — 48 hours — turns out to have a clause attached to it that changes the answer depending on which day of the week the arrest happened.

So here is the schedule, in plain terms: what the law actually requires, what usually happens inside that window, and what the numbers say about where a California felony case goes after it.

Key takeaways

• 48 hours is real, but it excludes Sundays and holidays. Penal Code § 825 sets the deadline for bringing an arrested person before a magistrate, and the exclusion means a Friday-night arrest and a Tuesday-morning arrest do not run on the same clock.
• Arraignment is not a trial and not a hearing on guilt. It is the reading of the charge, the entry of a plea, the appointment of counsel, and the setting of custody terms. It is short, and it is consequential mostly for what it schedules.
• Almost no California felony case ends in a jury verdict. Of 126,335 felony dispositions statewide in fiscal year 2024–25, 91,154 were guilty pleas entered before trial began and only 3,301 were decided by a jury.
• The preliminary hearing, not the arraignment, is where a felony case is usually shaped. It happens later, it is routinely waived, and waiving it is the decision worth understanding early.
• "Expungement" is the wrong word in California — the courts say so themselves — and since 1 October 2024 a category of record relief happens automatically, without a petition, for people who qualify.

What the 48-hour rule actually says

The requirement is statutory, and it is short. Penal Code § 825(a)(1) provides that the defendant

"shall in all cases be taken before the magistrate without unnecessary delay, and, in any event, within 48 hours after his or her arrest, excluding Sundays and holidays."

California Penal Code § 825(a)(1)

Two phrases in that sentence do the work, and most explanations skip both.

"Without unnecessary delay" comes first, and it is the real standard. Forty-eight hours is a ceiling, not an allowance. A person who could reasonably have been brought before a magistrate sooner is not lawfully held to the outer limit simply because the limit exists.

"Excluding Sundays and holidays" is the clause that surprises people. It does not mean the weekend is ignored — Saturday counts. It means Sunday and court holidays drop out of the count. In practice that is why the day of the week matters so much to how long someone sits.

Arrest	Days excluded	Realistic first appearance
Tuesday morning	None	Wednesday or Thursday
Friday evening	Sunday	Monday, sometimes Tuesday
Saturday	Sunday	Monday or Tuesday
Day before a court holiday	Sunday + the holiday	Can stretch past a long weekend

This is the single most useful thing a family member can understand on the first night. The question "why is nothing happening?" usually has a calendar answer rather than a sinister one. It is also why a weekend arrest is worth a call to a lawyer immediately rather than on Monday: the work that matters in that window — locating the person, understanding the charge, preparing for the custody decision — does not pause for the court's schedule.

What arraignment is, and what it is not

The first court appearance is brief. The charge is read or waived, a plea is entered — almost always not guilty at this stage — counsel is appointed if there is none, and the judge addresses custody: release on your own recognisance, conditions, or bail. Future dates get set.

What does not happen is any examination of whether the accusation is true. No witnesses, no evidence, no argument about the facts. People leave arraignment frustrated that "nothing happened," and in a sense nothing did. Its importance is procedural: it starts the clock on everything that follows, and the custody decision made there determines whether the rest of the case is fought from home or from a cell, which affects almost every practical thing about defending it.

Where the case actually goes

Television has given people a badly calibrated sense of what a criminal case is. It is worth replacing that with the state's own count of what happened last year.

The Judicial Council of California publishes the Court Statistics Report every year. For fiscal year 2024–25, the superior courts recorded 194,346 felony filings statewide and 126,335 felony dispositions. Of those dispositions:

• 91,154 were pleas of guilty entered before the start of trial — about 72 in every 100.
• 3,301 were decided by a jury. That is 2.6%.
• 154 were decided by a judge at a court trial.
• The rest, roughly 31,700, ended in other ways — a category the report notes includes dismissals and transfers, split between before and after the preliminary hearing.

Read that honestly and it reframes the whole exercise. The question in most felony cases is not "will a jury believe me." It is what the case is worth by the time anyone has to make a decision about it — and that value is set by what the evidence survives, which is decided long before a trial date.

That is why the preliminary hearing matters more than its reputation suggests. It is the one pre-trial proceeding where the prosecution's witnesses testify under oath and can be cross-examined, and it is waived constantly by people who were never told what it was worth.

The custody question in the first week

Whether someone goes home pending trial is decided early and is difficult to revisit. It turns on the charge, any record, ties to the area, and what the court is told about the person rather than the allegation. The practical point for families is that this is the one part of the first week where outside information helps: employment, housing, caregiving responsibilities, treatment history. None of it is in the police report. Somebody has to bring it.

The part nobody thinks about on day one

Most people arrested this week are thinking about the next fortnight. The part that determines the following decade is what the record looks like when it is over — and California changed how that works recently enough that plenty of advice online is now wrong.

First, the vocabulary. The California courts' own self-help guidance states plainly that "true expungement does not exist in California". What exists is a set of different remedies — dismissal after probation, reduction, sealing, automatic relief — each with its own eligibility rules. People search for "expungement," and the mismatch between the word and the remedies is where a lot of confusion starts.

Second, the automation. Under Penal Code § 1203.425, "commencing October 1, 2024, and subject to an appropriation in the annual Budget Act, on a monthly basis, the Department of Justice shall review the records in the statewide criminal justice databases" and grant relief to people who qualify — with no petition filed and no hearing attended.

The eligibility conditions are specific. The person must not be required to register as a sex offender and must not be under active supervision, and the conviction must fall into one of three situations: probation completed without revocation; an infraction or misdemeanour with one year elapsed since judgment; or a felony with four years elapsed since supervision ended without a new felony conviction. The statute excludes a serious felony as defined in § 1192.7(c), a violent felony under § 667.5, and any offence requiring registration under § 290.

And the relief is narrower than the word "clearing" implies. The same section requires disclosure "in response to a direct question contained in a questionnaire or application for employment as a peace officer," and states that relief does not "affect a person's authorization to own, possess, or have in the person's custody or control a firearm." Automatic relief is real and valuable. It is not an eraser, and anyone told otherwise should ask which subdivision says so.

Why this belongs in a piece about the first 48 hours: the plea entered in a case is what later determines which of these remedies is available. A disposition that looks equivalent today can be the difference between qualifying automatically and not qualifying at all. That is a reason to understand the endgame at the beginning, when there are still choices.

What to do in the first 48 hours

• Write down the booking details. Full name as booked, the facility, and the booking number. Everything else depends on locating the person.
• Assume calls are recorded. They generally are, and they are routinely used. Discuss logistics, not the allegation.
• Do not talk to investigators without counsel, and understand that the request has to be unambiguous.
• Collect what the court will not have — employment, housing, family responsibilities, medical or treatment history — before the custody decision, not after it.
• Get counsel involved before the first appearance rather than after. The custody terms set at arraignment shape the rest of the case, and they are argued once.

Questions we hear on this

Does the 48 hours include weekends?

Saturday counts. Sunday does not, and neither do court holidays. Penal Code § 825 excludes Sundays and holidays from the calculation, which is why an arrest late on a Friday can mean a first appearance on Monday or Tuesday while a Tuesday arrest usually produces one within a day or two.

What happens if the 48 hours passes and there has been no arraignment?

It is a violation of the statute, and it is raised with the court. What it does not automatically produce is a dismissal of the case. The remedy depends on the circumstances and on what, if anything, the delay produced — which is a question for a lawyer looking at the specific timeline rather than a general rule.

Should a plea be entered at arraignment?

A not-guilty plea at arraignment is ordinary and preserves every option. It is not a statement about the facts; it is a procedural position that keeps the case moving toward the stage where the evidence is actually tested.

Can charges still be dropped after an arrest?

Yes. An arrest is a police decision; charging is a prosecutor's decision, and they are not the same event. Cases are declined, reduced, and dismissed at several points, including before and after the preliminary hearing — the Judicial Council's own figures put roughly 31,700 of last year's felony dispositions in the category that includes dismissals and transfers.

How long does a California criminal case take?

There is no honest single number, and anyone offering one is guessing. It depends on the charge, the custody status, the evidence, and the court's calendar. What can be said is that the schedule is set in motion at arraignment, and the meaningful decision points arrive earlier than most people expect.

Does an arrest that never became a conviction stay on the record?

An arrest record can persist even where there was no conviction, which is why arrest relief exists as a separate remedy from conviction relief. Which one applies depends on how the matter ended.

Is drug diversion still available?

For qualifying offences, yes — and it changes the record outcome substantially, which is precisely why it belongs in the conversation early. We cover the mechanics in our note on PC 1000 drug diversion.
