Update (7:03 p.m. EST): The situation at the park remains peaceful, albeit with grumbles from those turned away. Police continue to monitor the protesters closely and are searching bags, but the mood is not confrontational. We're signing off for now, but will bring you updates when we come back on.

Update (6:48 p.m. EST): The mood is a big party, though not without strife. Protesters set up a buffet in the middle of the park, but police removed it, tweets Breaking911, an unofficial New York City emergency feed.

Update (6:27 p.m. EST): Cops read out the new rules for Zuccotti Park: Tents and sleeping bags are prohibited, as is lying down. Rumor in the park is that police will enforce a 10 p.m. curfew.

Update (6:20 p.m. EST): The NYCLU has been tweeting photos of people who got turned away from Zuccotti Park for having too-big bags or other things. This guy got denied because of his accordian:

Update (6:09 p.m. EST): Animal New York shares this photo of a triumphant-looking crowd touting their reoccupation of Zuccotti Park:

Update (6:07 p.m. EST): Protesters continue to stream back into the park, but some can't get in. Gillian Sneed tweets that medical and kitchen supplies have been stopped at the perimiter. And the NYLU tweets that people with even average-sized backpacks have been denied entry (follow the link for a photo). But the cops aren't the only ones denying people entry into the park. A few minutes ago, a Fox News crew got shouted down as they tried to do a broadcast. Eventually, they left to chants of  "na na na na hey hey goodbye."

Update (5:39 p.m. EST): The police have started opening the park to allow demonstrators back in, but they won't be allowed to camp. Animal New York reports via Twitter that police will stop people carrying "large bags." The live feed shows someone already setting up books under a taped-up paper sign reading "People's Library."

Update (5:06 p.m. EST): A "people's mic" has announced that a text alert went out to the occupation's master list, instructing supporters to come to the park at 5 p.m. to support the occupiers. Most of what's happened on Tuesday happened while people were either asleep or at work. As the workday ends, we could start to see a massive surge in numbers around the park.

Update (4:52 p.m. EST): The ruling has been posted in full on the court's website for your perusal. Below you can see the last-paragraph summary:

Update (4:45 p.m. EST): The latest on the verdict, according to the New York Daily News, is that protesters won't be allowed to camp in the park after all.

Update (4:40 p.m. EST): The word on Twitter now is that the verdict on the injunction allowing protesters back into the park will be read at 5 p.m.

Update (4:36 p.m. EST): The UStream guys are interviewing the hipster cop. He says his signature glasses were originally shades, but he took the lenses out and got prescription ones put in. Now you know! Also, he told The New York Times he didn't even know about the raid until he got to work on Tuesday afternoon. Here's a screenshot:

Update (4:07 p.m. EST): After disheartening reports on Tuesday that the contents of the Occupy Wall Street library had been destroyed, The New York City mayor's office tweeted the below photo from its official stream. At least some of the books are safe in storage:

Update (3:42 p.m. EST): The crowd is chanting "let us in" and "open the park" quite loudly. Andrew Katz tweets this insight about the potentially volatile situation:

But while it's loud as all get out, the crowd does seem peaceful.

Update (3:34 p.m. EST): An announcement just came down at Zuccotti Park that the Huffington Post and CNN had reported the court had ruled that they could return to the park. But so far nothing official has come through. It seems an eager crowd jumped the gun, reading a post from earlier Tuesday that reported on the temporary injunction from the morning.

Update (3:21 p.m.): An antsy crowd becomes a little restless waiting for the expected verdict on whether protesters will be allowed back into the park. The official Occupy Wall Street Twitter account says one protester has been arrested in the last few minutes as the "crowd jostles with riot police in helmets."

Update (3:11 p.m. EST): It's starting to rain in Downtown Manhattan. Still no word of a verdict, but word is it may have been pushed back to 3:15 p.m.

Update (2:54 p.m. EST): The destruction of the Occupy Wall Street library overnight went down especially hard with some. Boing Boing relayed tweets from the librarians that some 5,000 books were thrown away. Now, word comes via Twitter that the site Library Thing has the entire catalogue. It's a neat detail in an otherwise depressing eddy of Tuesday's news. Provided they get let in, the plan is to rebuild the People's Library at 6 p.m. Tuesday.

Update (2:33 p.m. EST): NBC New York reports that the city has closed a garage where it was storing things police seized at Zuccotti Park Tuesday morning. Sanitation Department workers said broken glass amid the piles of belongings posed a safety hazard.

Update (2:24 p.m. EST): Ydanis Rodriguez, the New York City Council member arrested early Tuesday morning as part of the sweep of Zuccotti Park, is still in custody.* At a press conference to discuss his arrest, his council colleague Tish James said his legal team still hadn't been able to see him, tweets New York Times reporter Kate Taylor. Taylor also tweeted: "Ppl at @ydanis presser using human mic to report on proceedings in courtroom; report that "it looks positive," triggers twinkle fingers."

*Correction: This update initially said Rodriguez had been released from custody. He has not.

Update (2:03 p.m. EST): Primary document fans can take a look at the city's filing in response to the injunction against it courtesy of The New York Times posting on Document Cloud. In short, deputy mayor Cas Holloway argues in the document that the protest encampment represented a safety threat, and that protesters detracted from the neighborhood's quality of life.

Update (1:57 p.m. EST): On Twitter, the buzz from many sources is that a verdict in the injunction hearing is expected to come down by 3 p.m. Meanwhile, at Zuccotti Park, protesters mill around, drumming and cracking wise about the cops and private security (those in the green vests, someone told our live feed cameraman) who continue to guard the empty park:

Update (1:39 p.m. EST): The legal wrangling continues at Manhattan Supreme Court. City Hall News has some good updates on the arguments via its Twitter stream:

Update (1:29 p.m. EST): For a bit of background on Tuesday morning's legal wrangling, The Daily News's Celeste Katz posted both the letter from Brookfield requesting the eviction, and the temporary court order telling the city to allow protesters back into Zuccotti park.

Update (1:20 p.m.EST): Lawyers for the city are making their case before Judge Stallman, arguing that protesters in Zuccotti Park pose a safety threat. The New York Times tweets: "City tells court, "Protesters may have had significant number of items that could potentially be used as weapons." Incl. mace, knives. But lawyers for the occupation say "this isn't a camping case, like Brookfield is arguing, but a free speech case," according to City Hall News's Twitter. Furthermore, "OWS lawyer argues Brookfield created no camping rules in response to occupation. Determined response to free speech activity." Meanwhile, the live feed at UStream reports that a march from Duarte is starting to arrive at Zuccotti with as many as 500 people.

Update (12:38 p.m. EST): Judge Michael Stallman has been assigned to the hearing on a court order to allow protesters back into Zuccotti Park, tweets The New York Times. You can read his official profile here, for starters. Meanwhile, the actual location of the hearing seems to be causing a problem for those trying to attend. Tweets writer Nancy Scola:

Update (12:31 p.m.EST): Protesters who remained at Duarte have decided to march back to Zuccotti in anticipation of a court order they hope will allow them back in. A judge is expected to rule at any minute on whether the city had cause to evict the Zuccotti encampment.

Update (12:20 p.m. EST): Police have cleared Duarte Square entirely, Student Activism reports, sharing this photo:

Update (12:15 p.m. EST): More reporters have been arrested at Duarte. The New York Times tweets: "Looks like about 2 dozen arrests at church-owned lot next to Duarte Park at Canal St., incl. journos from AP, DailyNews, DNAInfo." Christ tweeted that "about 30 people" had been arrested during her live broadcast from the park.

Update (12:10 p.m. EST): Student Activism reports "Everyone inside fenced area of Duarte has been arrested." That includes New York Daily News reporter Matt Lysiak, according to The Daily News's Twitter. The New York Times tweets Trinity Church officials said of protesters, "we didn't invite those people in."

Update (12:01 p.m. EST): "Police are arresting and beating people at Canal," reports Occupy kitchen volunteer Megan Hayes, in a text message. Christ reports people are hanging from the Duarte fence "with their bodies on the outside for easy escape." The ACLU reports "at least 10 arrests" via Twitter.

At the same exact time, a guy broke through the police line at Zuccotti Park, carrying an American flag into the park, the live feed showed. Police immediately arrested him. It appears it was the same flag from below, which protesters promised to return to Zuccotti earlier.

Update (11:57 a.m. EST): The Daily News has more on that judge who signed the court order allowing protesters back into Zuccotti. She's not going to stay on the case because she usually handles real estate cases. The judge in Tuesday's hearing will be chosen electronically from a list that doesn't include her, simply because such cases aren't usually her specialty.

Update (11:52 a.m. EST): Police are reportedly preparing to move in and arrest protesters at Duarte, Christ reports via Twitter. "A few remaining occupiers are barricading near gate. More cops in riot gear moving in."

Update (11:43 a.m. EST): The encampment in Duarte Square seems to be gaining strength. The New York Times reports that at about 11 a.m. protesters cut the lock on a patch of land adjacent to the square and owned by Trinity Church. Now, police and protesters are standing off at Duarte, Christ reports. A tent has gone up at the new site, Student Activism tweets, and "hipster cop" Rick Lee has arrived, so you know this new site is legit (photo via Daniel Albanese):

Update (11:15 a.m. EST): The live feed is back up, showing protesters milling around a Zuccotti Park completely surrounded by barricades and riot police. Meanwhile, NY1 reporter Lindsey Christ tweets that protesters at Duarte are jumping a fence in order to occupy a closed-off portion of the park. She shared this photo:

And this one:

And the live feed via UStream:

Update (11:01 a.m. EST): The New York Daily News explains how protesters got the court order allowing them back into Zuccotti Park signed at 6:30 a.m. Their legal team reportedly called Manhattan Supreme Court Justice Lucy Billings, who has a background with the ACLU, and asked her to sign the order, which she did. But Billings won't necessarily preside over the hearing today at which the city must show cause for the eviction.

Update (10:44 a.m. EST): The live feed is down thanks to a dead battery, but The New York Times reports police have started making arrests as several protesters tried to jump the barricade. Also, reporter at large Harry Siegel tweets

Update (10:40 a.m. EST): Protesters have started massing around the park, with police blocking them from entering. CNBC's Kayla Tausche tweeted this photo of the crowd massing on the north side of the empty park:

Update (10:25 a.m. EST): The protesters made it to Zuccotti Park, but police still have barricades up and are apparently not letting anyone in. News 12 Brooklyn reporter Stephanie Ramirez tweets this photo:

Update (9:54 a.m. EST): Live stream estimates 100 to 150 protesters are walking back to Zuccotti Park from Duarte to try to get in ahead of the 11:30 a.m. hearing at which the city must show cause for their eviction. As it stands, a judge has enjoined the city to allow protesters into the park, but that could change if the city sufficiently justifies its eviction of the encampment before the judge. Another group of protesters opted to stay at Duarte Square and hold it. Occupy Wall Street's official Twitter account sent this photo:

Update (9:30 a.m. EST): A protester explains to the live stream cameraman that police barricades remain in place around Zuccotti Park in spite of the injunction allowing protesters' return, so a general assembly at Duarte Square decided to stay at Duarte, which is owned by Trinity Church. The church reportedly told the protesters they could stay. But a contingent seems to be preparing to leave for Zuccotti.

Update (9:10 a.m. EST): Protesters have arrived at Duarte Square, at Sixth Avenue and Canal Street. The live stream of the protest shows police surrounding them in the park as one guy tries to spread the word of the court order allowing protesters to return to Zuccotti. Protesters start chanting "let's go home!"

Update (8:50 a.m. EST): The march continues, but police are keeping a tight grip on the situation. After blocking protesters' access to City Hall, they've temporarily closed Broadway but are also keeping protesters on the sidewalk, Alex Goldmark tweets this photo:

And cops will reportedly be searching protesters as they return to Zuccotti, according to The New York Times' Twitter:

Original: With a judge issuing a temporary order allowing protesters, with tents if they choose, back inside their former encampment at Zuccotti Park, protesters who had regrouped at Foley Square, about 12 blocks north of Zuccotti,  have already started marching back.

Dashiell Bennett has the full details on what happened at Zuccotti over night. Protesters began arriving at Foley Square, around 4 a.m., and by 8 a.m. a kitchen had been set up, drummers drummed, and a crowd had arrived en masse. The protesters started moving from Foley at around 8 a.m., with the plan to march from back to Zuccotti via City Hall (where Mayor Michael Bloomberg is holding a press conference) and the intersection of Canal and Sixth Avenue. But according to Firedog Lake contributor Cynthia Kouril, police blocked them from City Hall.

A judge ruled this morning that the police couldn't keep protesters and their gear from Zuccotti Park (see below) but scheduled a hearing for 11:30 a.m. Tuesday morning where the city will need to "show cause" for its eviction of the protesters. Reuters's Anthony De Rosa tweets this guy promised they would plant this flag back at Zuccotti:

Meanwhile, The New York Times reports via Twitter that a judge has already ruled the protesters can return, with their gear. Check out a copy of the judge's order.

Student Activism's Angus Johnston shared this Lockerz photo of the crowd getting ready to march back to Zuccotti:

The neighborhood where the protesters are marching spans downtown, from Canal Street down to Zuccotti Park:

We'll keep you posted as updates come in.
