The Caledonian Habitation Zone is the irradiated remains of Scotland, which for years was under Brit-Cit control. The largest settlement is Glascal.
Cal-Hab is also the home of trashzine artist Kenny Who?.
The population is famed for violence, deep-frying everything, drunkenness and penny-pinching - Prog 1540 revealed it has only two charities and one of them is campaigning for an increase in miserly behaviour.
Scotland had an oil boom in the 1980s that saw dozens of new townships built around the coast; when the oil ran out, the townships became destitute and the former oil men turned to the sport aeroball. The Flying Scotsmen aeroball team had a reputation as the toughest in the world.
The trauma of the 2070 Atomic Wars caused the Scottish to regress to an apocryphal Highlander past. These "Caledonian Wastes" were looked down on as a lawless wasteland by the new global community, and it was used as a dumping ground for toxic and nuclear waste (particularly the Dounreay Contam-Zone).
In order to bring the country to order, Brit-Cit set up the Song-in-the-Sky satellite network to bombard the locals with subliminal messages, making them more controllable (and more 'comedy stereotype'). The Baxter Genepool project, started in the 2080s, began to create a breed of future Judges. Finally, the newly established Cal-Hab and its Judges were accepted into the world community in 2101: once again under the rule of Brit-Cit.
In the 2110s, the Judges observed a hogmany amnesty for minor crimes.
There was a large amount of nationalism and desire for Cal-Hab to be independent in the 2110s, but the whisky clan factions spent too much time fighting each other to be a credible resistance. (However, in 2129, Dredd and a Brit-Cit Judge remarked that Cal-Hab had been mostly independent for a century, which had not stopped hard-line nationalist paramilitaries from trying to separate the state completely from Brit-Cit - literally, with explosives.) The New Old Bailey sent a quota of Judges up north on six-month tours. The locals gave them all the dirty jobs. The local Judges, if good, would be headhunted for Brit-Cit and they had so few psis, they only had one empath in Judge Schiehallion. (When he wouldn't risk himself and a civilian died in 2115, Chief Inspector James Bryson deliberately destroyed the report rather than lose Schiehallion)
In 2114, the Campbell and Abercromby whiskey clans began peace talks and the Judges agreed to supervise. It turned out the Campbells had stolen the Stone of Destiny from Brit-Cit (who implied to CI Bryson that they meant nuke Cal-Hab if it got too unruly) and were planning to kill Chief Banger Abercromby & unite all the clans to take possession over Cal-Hab. Judge Ed MacBrayne stopped the plot but broke the Stone in the process.
A 'terrorist attack' was launched on Dounreay in 2114 and armed Judges fought off the cybernator attack - actually the cover story for mercenaries hired by a South-Am City company that wanted Dounreay out of the energy market. MacBrayne was hospitalised stopping the plant from being blown up, while South-Am denied all knowledge.
In 2116, empath Judge Schiehallion went mad and became the conduit for supernatural entities. After being shot, he rose from the dead, had a second breakdown, revealed the Song-in-the-Sky satellite to the public, and then destroyed it. The absence of the satellite's signals caused Cal-Hab to descend into tribal violence and the Judges were either massacred or formed into their own tribe, the Knights of the Templar. A Brit-Cit Psi-squad led by "Brit-Cit Brute" was sent in but defeated, and eventually Schiehallion covered most of Cal-Hab in a huge psychic storm known as the Flux, which has left a large part of the territory beyond anyone's control or comprehension.
Since then, most of Cal-Hab seen has been rural. There is still reference to "Cal-Hab law" and there is a Ness International Hoverport and direct zoom trains to Mega-City One. In the wilds outside of the habzone proper lived the "wild Scotties", who only enter to forage illegally and aren't protected by the law; this left them open to exploitation by body-brokers, implanting the brains of rich, elderly clients into young Cal-Habber bodies.

The area has its own semi-autonomous Judge force, run by a Chief Inspector. The Judges have added a Celtic helmet and kilt to the British uniform. The Judges themselves were genetically tweaked to be immune to low-level radiation.
Traditionally, all judicial decisions are made from Brit-Cit and the best Scottish Judges were head-hunted for Brit-Cit roles, leaving the Cal-Hab Judges demoralised.
Many pubs are "Judge Free" zones.
Post-2116 Cal Hab still possesses a Judge force but it ignores the plight of the wild Scotties. In 2126, Chief Inspector McKinty appeared as part of a separate delegation to the Global Justice Summit instead of with the Brit-Cit group. 
Cal-Hab has had multiple cameo appearance's in the stories of Wagner and Alan Grant, nearly all of which are played for laughs and which focus on Scottish humour. Jim Alexander's Cal-Hab Justice, on the other hand, was often quite grim and focused on political allegories for mid-90s Scottish issues; the city-state was also shown to be under heavy Brit-Cit control. Gordon Rennie's "Judge Dredd: Tartan Terrors" (#1540) played Cal-Hab for laughs but in a slightly more aggressive manner, such as introducing penny-pinching as a Cal-Habber trait (an old Scottish stereotype); it also referred to Cal Hab as having political independence for a century. In the letters page for #1547, editor Matt Smith (via Tharg the Mighty) openly admitted that Gordon Rennie was ignoring Cal-Hab Justice.
Cal-Habbers are usually written with heavy, phoenetic accents and Scottish slang, making them indecipherable for foreign characters. (This is a traditional way of writing Scottish characters in Scottish comics, as seen in Oor Wullie and The Broons)
"Harlem Heroes" made note of the contemporary oil boom and the calls for Scotland to be independent on the back of it - the strip has been grandfathered into Dredd history, making Scotland independent sometime in the late 20th or early 21st century.
