We saw a landmark decision last week in U.S. courts.
One that could become the biggest new driver for North American natural gas prices.
The decision came in the supreme court of Pennsylvania. Where judges voted 4-2 to overturn new laws that limited the ability of municipalities in the state to regulate hydraulic fracturing for oil and natural gas drilling.
Pennsylvania's Republican governor Tom Corbett had previously announced the laws in an attempt to limit local bans on fracking. Several such moratoriums have been pursued by cities and counties in Pennsylvania. And around the country.
The new laws looked to be putting regulatory power firmly back in the hands of the state government. A move that would have streamlined oil and gas development here.
But no more. With the laws now overturned by the supreme court, municipalities will be free to impose their own bans on fracking. Effectively halting development in such locations.
The decision comes at a crucial juncture for natural gas prices. Pennsylvania's Marcellus shale is today the biggest driver of growth of in U.S. natgas production. Output here continues to soar, while other big shales like the Haynesville are actually declining. Even production from go-to drilling acreage in the Eagle Ford play has been growing much more slowly of late.
That could change if the new shift in rules causes a drilling slowdown in Pennsylvania.
Putting a crimp in America's most productive shale gas play. And potentially levelling production.
That would of course be supportive for natgas prices. Potentially speeding gains in this space, which is currently being weighed down by Pennsylvania's prolific output.
Last week's ruling may in fact accelerate the pace of opposition to fracking. As part of the decision, the presiding Chief Justice Ronald Castille took an unusual step: declaring that gas drilling is dangerous. Castille wrote decidedly that fracking has a "detrimental effect" on the environment, and compared it to coal mining.
Legal experts have noted such sentiment likely oversteps the bounds of the court. But it may nonetheless tip some communities against drilling. Leading to more local bans.
We'll see how far this spreads across the state. And how quickly the resulting production losses start to affect pricing in this market.
Here's to courting some gains,
